Thank you for your asreg package, which is very useful to me. I am trying to estimate the Fama-Macbeth regression. The analysis is based on asset returns and factor returns published on Professor Kenneth French's data library. It has a significant number of gaps which the newey() option cannot handle. Second, compute time-series averages returns Rbar. Can you please share the dataset that can reproduce the error. Stat/Transfer is a cute tool to switch the data types. Hence, academics and developers have not bothered about coding the model without a constant. I have a panel dataset with monthly fund returns from which I wanted to get the average alpha using the fama french 3-factor model. Third, run the following cross-section regression. progress: Logical: If TRUE, the progress of the estimation is printed to the standard output. Fama MacBeth Regression. Testing Asset Pricing Models Time Series Regression testing 1 Testing Asset Pricing Models Introduction Thanks for sharing useful resources. Gabriel Following are the detail of this project: Importing different files from Excel Please your answer to the question was “Jon, Thanks for sending me your dataset. So if we were to use two lags with the Newey-West error for the above command, we shall type; For some reasons, if we wish to display the first stage N – cross-sectional regressions of the FMB procedure, we can use the option first. Thanks for your avialability. Fama MacBeth says do the regression every period (usually years). And if we wish to save the first stage results to a file, we can use the option save(filename). The standard errors are adjusted for cross-sectional dependence. This function takes a model and a list of the first stage estimates for the model and does the second stage of the Fama-MacBeth regression. Do you have an idea what Iâm doing wrong? # Google shows that the original paper has currently over 9000 citations (Mar 2015), making the methodology one of the most I re-exported again and the mean figures seem to match up now. I am using: asreg fund_return mktfrf smb hml, fmb. Is there a step to perform before using asreg fmb to get variant variables or would an xtset to time id help? Hi professor, thank you so much for your post and help overall. The post can be read here. However, at the moment, there is a workaround and you do not need to wait for the updated version. So once I get these lambda_t's, I could for example calculate a t-statistic by averaging my 252 values and divide by the sd? A bit of code was missing which I have added. Stata is easy to use but it is a little painful to save the outputs. Risk, Return, and Equilibrium: Empirical Tests Eugene F. Fama and James D. MacBeth University of Chicago This paper tests the relationship between average return and risk for The asreg full command that you have used. Thanks for sending me your dataset. If you look at your data, first three periods of firmid 1 and 2 as an example, the values are the same, which might be the case for other firmids as well. thanks for your detailed answer but unfortunately your example does not fit mine dataset. Using the grunfeld data, asreg command for FMB regression is given below: If Newey-West standard errors are required for the second stage regression, we can use the option newey(integer).Â The integer value specifies the number of lags for estimation of Newey-West consistent standard errors. Safi Ullah Atthullah If you are interested, you can drop me an email at email@example.com. The objective is to match the desired factor loads while optimizing other factors like costs, (negative) alpha, diversification, taxes, etc.The basic steps are: 1. Thomas The standard errors are adjusted for … Hi all, i'm trying to understand Fama - Macbeth two step regression. Statistically speaking, there is a general agreement on “the more, the merrier”, and this is the case with the monthly data as compared to quarterly data. The site may not work properly if you don't, If you do not update your browser, we suggest you visit, Press J to jump to the feed. Re … Therefore, commands for these options will look like: Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â First stage Fama-McBeth regression results, FMB regressions with 25-portfolios â An example, Antonio has asked the following question Dear Sir, I was wondering how to run a…, Fama and MacBeth (1973) procedure can be used in testing asset pricing models and in…, Hope you are fine and in good health. I do not patrons who would support in adding further features to asreg. Is it possible to generate the adj. Is it possible to receive cross-sectional residuals for each firm with this method? Risk, return, and equilibrium: Empirical tests. Antonio There was a lengthy discussion on this issue on Statalist, it might be helpful for you. Marie He states that "whether there is a bias in the traditional Fama–MacBeth approach if expected returns vary with time-varying characteristics is still unexplored.". this will cause asreg to first estimate a time series regression for each company and then report the averages of those time series regressions. I have some queries regarding asreg. second, how about the ” xtfmb ” command? First of all, thank you for your website it has been great support to me. Thanks, I just checked the data points and noticed that the -ve signs for some of them changed to positive after I exported the table to excel. Dear Sir, Readers might not read the full story and quickly jump to do what you are asking for. However, in 7 of the years I only have 62-128 observations while I have 150-600 yearly observations in the following 20 years. Reason being that Fama and MacBeth (1973) did not use any variation of their model without a constant. Note that FM estimates per-period prices of risk, and then averages over time, while the cross-sectional regression averages returns over time, and estimates a single price of risk. There is no standard to which a lower or higher value can be compared. I am a little bit unsure how I should understand the procedure. TheÂ Fama-McBeth (FMB) can be easily estimated in Stata usingÂ asregÂ package.Â Consider the following three steps for estimation of FMB regression in Stata. Can you please share the above with my dropbox email firstname.lastname@example.org or simply email these. I am one of your student from Bara-Gali workshop, I am applying Fama and Macbeth regression on Pakistan Stock exchange firms on monthly data (Data sheet attached herewith). However, my data is monthly for 10 companies and 5 independent variables. I was wandering how to run a Fama and MacBeth regression over 25 Portfolios. This is against the spirit of Fama and MacBeth (1973). GMM, essentially a two-pass regression, better robustness, however. Press question mark to learn the rest of the keyboard shortcuts. Pattrick Does this mean that you estimate one regression for each year across the firms? Downloadable! So the final step would just show the averages of the coefficients estimated in the first step. Can you recommend any alternative? Thank you for the detailed and understandable explanation. I saw some of the literature reports regression coefficients of Fama-French factor with Fama-Macbeth procedure. Fama and Macbeth (1973) regression(by Dr. Jeff Wongchoti)Fama and Macbeth regression is “a special type of regression methodology (very)widely used in financial research to handle panel data” (data series with both crosssectional (e.g. To understand the FMB procedure, you should first study Fama and MacBeth(1973) paper and relevant literature elsewhere. I tried to alter the xtset command and was able to get the results. To add some detail to /u/Gymrat777's explanation, suppose that your asset returns are R_it and your factors are F_t. R^2 variable? Value. You have to dig deep and read the literature of the relevant field. A sample of your data that generates the said error Fama and MacBeth, "Risk, Return, and Equilibrium: Empirical Tests". Hi all, i'm trying to understand Fama - Macbeth two step regression. The procedure is as follows: In the first step, for each single time period a cross-sectional regression is performed. And in the second step, all those cross-sectional coefficients are averaged across time periods. The updated version can be downloaded from SSC a week or so. New comments cannot be posted and votes cannot be cast, More posts from the econometrics community, Looks like you're using new Reddit on an old browser. is it OK? However, if both cross-sectional and time-series dependencies are suspected in the data set, then Newey-West consistent standard errors can be an acceptable solution. I have a question however, regarding the time period of the formation for the betas. I have been using the fmb-procedure during my dissertation and it has been working like a charm! I am investigating the relationship between Abnormal Google Search Volume and Abnormal Returns. The reason I am not showing the command to do that in asreg here is the potential misuse. Please note that without using option newey, asreg estimates normal standard errors of OLS. it means that he runs a single cross-sectional regression each month and forms the point estimates and standard errors from the time series of these estimates, probably not exactly, but this is not so important (people use Fama-MacBeth in many contexts where the individual estimates are not independent), and; I … Seppo Pynn onen Empirical Asset Pricing. Institute of Management Sciences, Peshawar Pakistan, Copyright 2012 - 2020 Attaullah Shah | All Rights Reserved, Paid Help â Frequently Asked Questions (FAQs), Fama and MacBeth (1973) Fastest regression in Stata, Fama and MacBeth regression with Shanken correction using asreg, Fama and MacBeth regression over 25 Portfolios using asreg in Stata, Fama - MacBeth (1973) procedure: What, how and where | asreg in Stata, Customized tables using option row() of asdoc – Stata, https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3081166, Measuring Financial Statement Comparability, Expected Idiosyncratic Skewness and Stock Returns. If we can, how can we use asreg for it? In accordance with your code, the first variable needs to be the dependent variable while the following variables are considered as independent variables.. Basically I would like to calculate the risk premium of a factor over the 25 value ans size sorted portfolios. The data is collected from S&P 500 with a time-span of 5 years. I realize that the procedure theoretically doesn’t include specific companies and basically pull a random sample, but I have a rather consistent, yet unbalanced, panel. If you want to report the first stage results, then just add first to the fmb option as shown in the blog above. Shaika Thanks for your reply. The first is to estimate as many cross-sectional regressions as the time periods. Sometimes it is convenient to handle raw data in SAS and then perform statistical analysis in Stata. Moreover, he says that "autocorrelation in returns (negligible at monthly frequency) leads to autocorrelation in risk premium estimates. Is it possible to derive the adj. The F-value is directly reported from the mvreg regression that is estimated for all the cross-sectional regressions of the first stage of FMB. Currently, asreg does not support the noconstant option with Fama and MacBeth regression. Thank you so much sir. In other words, you are using the lag length of 8 with the newey() option, however, the gaps in your date variable are larger than 8 units and hence you get the error of no observations.” Please is there a way to fix this? Say I have returns/betas for 100 stocks and one year (252 periods). Not entirely sure where to go from there? “Table 2 shows by-fund average fund performance with Fama and MacBeth (1973) standard errors based on monthly returns.”. Just leave me an e-mail adress where to send it to. Michael Cooper, Michael Halling and Wenhao Yang – The Mutual Fund Fee Puzzle. Mathias It mentions, The Fama-McBeth (1973) regression is a two-step procedure . 1973) two step procedure. asreg is much faster, and the difference in calculation time balloons as we use more data. The method estimates the betas and risk premia for any risk factors that are expected to determine asset prices. Method was inspired by: Lach (2002) – Existence and Persistence of Price Dispersion: an Empirical Analysis You may read several papers on this topic in your domain of research and see how low is the r-squared of your model. Thanks again for your availability, Yes, cross-sectionally invariant variables will be omitted in Fama and MacBeth regressions. By the way is alpha the residual? See the case of the first month: and you shall see that all the values of this variable are the same within the given month, and is also the case with other months; therefore, the regression does not find any variation in the dataset to fit the model. We find that the convergence of the OLS two-pass estimator depends critically on the time series sample size … In the first step i compute 10 time series regressions and if i have 2 factors i get 20 betas. In any given month, BW is either 0 for all observations or 1 for all observations, therefore coefficient has to 0. Hello Gerad Ong Is there a way to fix this, so that for example dummy5 is the reference group over all months? Posted on August 14, 2013 by SAS Code Bank. I get the same result as using “asreg”. I have an additional question. Determine equity / fixed income split - (Asset Allocation) 2. The Fama–MacBeth regression is a method used to estimate parameters for asset pricing models such as the capital asset pricing model (CAPM). If NULL, the internal function is used. The Fama-MacBeth Approach • Fama and MacBeth (1973) used the two stage approach to testing the CAPM outlined above, but using a time series of cross-sections • Instead of running a single time-series regression for each stock and then a single cross-sectional … (3) Usually, lower r-squared is an indication of omitted variable bias. As you have mentioned yourself, this option is not yet available and would a sufficient amount of time. A sample of the data I use is attached at the bottom. I produce consistent estimates and correct the time-series dependence with newey-west errors. As an aside, the way I think about the difference between cross-section and FM regression is cross-section equally weights each observation where FM equally weights each period. Lot’s of people, apparently… Welch (2008) finds that ~75% of professors recommend the use of the model when estimating the cost of capital, and Graham and Harvey (2001)find that ~74% of CFOs use the CAPM in their work. So in my case, I calculated all of my betas based on all of the stock data I had (open/close/high/low/volume etc.). Example: Fama-MacBeth regression Estimating the Risk Premia using Fama-MacBeth Regressions ¶ This example highlights how to implement a Fama-MacBeth 2-stage regression to estimate factor risk premia, make inference on the risk premia, and test whether a linear factor model can explain a cross-section of portfolio returns. I run the regression in order to control for heterogeneity within mutual funds, and I wish to study the residuals over time in order to study price dispersion. This is generally an acceptable solution when there is a large number of cross-sectional units and a relatively small time series for each cross-sectional unit. I obtained the following macro program: %macro FamaMacbeth(dset, depvar, indvars); /******run cross-sectional regressions by fyear for all firms and report the means. Anyway, thanks for reporting this and bringing it to my attention. xtfmb is an implementation of the Fama and MacBeth (J. Polit. Fama and McBeth regressions are cross-sectional regressions estimated in each time period. Fama-Macbeth rolling estimation procedure. It is hard to tell. here is a link to one paper: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3081166 sort year egen nogap=group(year) xtset id nogap asreg y a b c e f, fmb My question is how to estimate the statistical difference between coefficients e and f. My coefficient e is -.4804889 and coefficient f 1.518726. A similar issue is reported every now and then on Statalist. but, how can I choose the lag when using “xtfmb”? Thanks for your response. In fact when I try to use your code I do not get any coefficient for the market risk premium. I'm trying to create a factor model on equities based on a paper I've read. 2.Â Install asreg from ssc with thisÂ line of code: We shall use the grunfeld dataset in our example. I tried using FmB across the entire 27 years, however the results is significantly different from the result I obtain when only using the T=20. The Fama-French factors are panel invariant variables and thus the variables get omitted. Contrast with what is commonly called the cross-sectional regression approach: First, do the same first stage as FM to get beta's. Running a Fama-Macbeth regression in SAS is quite easy, and doesn't require any special macros. Your gspc_return variable seems to be constant within a given period. Rbar_i = lambda * beta_i + a_i. Two-pass regression. Dear all, Good days to everyone here. Dear Sir, The following code will run cross-sectional regressions by year for all firms and report the means. I have 10 portfolios and T=5 years. It has a significant number of gaps which the newey() option cannot handle. Basically right now I have my returns and factors that I calculated for hundreds of stocks over the past several years. The independent variables are standardized and all rows containing NA are removed. The Fama-McBeth (1973) regression is a two-step procedure . This is way better than my response. Where the appropriate test is one which tests if a_i is zero. Therefore, the author does not estimate cross-sectional regressions in the first stage of the Fama and MacBeth (1973) procedure. First, let's look at the OLS regression by using the pandas.ols function as follows: Copy. however when I add zfc variable, it has some missing value, the results are as follows. If your literature allows that, then asreg can very easily implement that. I found that my results are significantly different when using T=27 and T=20 due to the limited data in the first years. asreg command does not ommit it. I am very thankful for your response, have a blessed day! Turns out the problem is not with asreg, it is with your date variable. Econ. R^2? Reference It’s a question of theory. Personally, I am testing the Arbitrage Pricing Theory model using the Fama Macbeth procedure. To answer your question, I have written this post. Please also let me know about any coming workshop on Stata. 1. So I am looking for any critique that may be of putting relatively large weight on the 7 years (weight 26%) to betas estimated on only approximately 9% of the total firm years. Fama-Macbeth regression in Table 10 does not make sense. Third, run the following cross-section regression. # In my portfolio, I show how the popular Fama-MacBeth (1973) procedure is constructed in R. # The procedure is used to estimate risk premia and determine the validity of asset pricing models. Turns out the problem is not with asreg, it is with your date variable. Now calculate the average and std error from that set of 20 years and report results for beta1, beta2, etc. I was thinking of cutting the period, because the reliability on the first 7 periods may influence the total estimate. However, I was unable to find more information online on this issue. If you cannot still figure it out, then you can consider our paid help. That means the difference e … (2) Yes, xtfmb and asreg produce exactly the same result, the only difference lies in the calculation time. Thomas I understand fama french, I'm a little confused on what fama macbeth is and how it is different and how it is applied here. is it OK? It says they use fama macbeth regressions. Two Stage Fama-Macbeth Factor Premium Estimation The two stage Fama-Macbeth regression estimates the premium rewarded to a particular risk factor exposure by the market. Thank you Prof. Can you give full references to those papers here and copy paste the relevant text from them? This article describes the end-to-end process to create and maintain a portfolio. excuse me already from the start for the lengthy post. However, I have problems using the fmb on my data set. Second, compute time-series averages returns Rbar. Regressing time series first would be the only option to avoid cross sectional invariance in this case. moreover, the R2 is not so good. I am sorry for your precious time. Here are a few: 1. I have a panel dataset were T=27. When I set xtset Fund Time I always get omitted variables. Hi Sir, dear sir, Where the appropriate test is one which tests if a_i is zero. Bonus yet, you can the first stage regression ouptut in a file. Jon Can we not use time series regression first and then cross-sectional in step two to avoid cross-sectional invariance of fama-french factor? Re: Adj R squared in Fama-MacBeth Regression Posted 07-24-2013 11:20 AM (2553 views) | In reply to mexes I really don't have an answer, but I would bet that someone on the Forecasting and Econometrics forum would be able to help with the PROC MODEL part. You might be missing some important steps of the papers you are referring to. The project uses a variety of empirical methods used in IPO research. Perform Fama-French three-factor model regression analysis for one or more ETFs or mutual funds, or alternatively use the capital asset pricing model (CAPM) or Carhart four-factor model regression analysis. What I meant was to share text from the mentioned papers that use Fama and French factors in Fama and MacBeth (1973) regression. This will require fundamental change inside the asreg code. finally, in my data, T=42. In the first step i compute 10 time series regressions and if i have 2 factors i get 20 betas. You get a collection of regression coefficients, say 4 coefficients (beta 1-4) for each of 20 years. The method works with multiple assets across time ( … I have several questions about my regression in using Fama MacBeth regression. You say the explanation is “…however, the gaps in your date variable are larger than 8 units and hence you get the error of no observations.” How do you cope with this? Currently, I am a bit over-burdened and cannot find enough motivation to do that. Therefore in my case i would have more dependent variables and just one dependent variable. first, my data is quarterly data. I was running Fama Macbeth 2-stage regressions (stage 1) and saw discrepancies in the means from the output table below and the one computed by excel – for the slope coefficients and intercept (see attached excel working and below output table). Is this the way of doing it? Rather, he estimates time series regression for each fund, and then finds averages across all firms. Thank you for the reply. I am referring to the description of table 2 in specific. Whenever we want to compute Fama and Macbeth model without intercept. What about when I regressed against excess global premium it omitted the said variable and only report constant. But why are so many research papers state that they are using FMB in this context since they all face the same problem? Choose Specific Funds for Each Region 4. asreg works just fine without newey, but when newey is included I am unable to run it. I have 10 portfolios and T=5 years. The procedure estimates a cross-sectional regression in each period in the first step. Contrast with what is commonly called the cross-sectional regression approach: First, do the same first stage as FM to get beta's. In that case, do I not need to regress for the betas? hello, I would like to do Fama MacBeth regression and i used xtfmb function. Then, in the second step, the final coefficient estimates are obtained as the average of the first step coefficient estimates. The first step involves estimation of N cross-sectional regressions and the second step involves T time-series averages of the coefficients of the N-cross-sectional regressions. Thanks for the feedback and asking about the possibility of generating residuals with FMB. Happy to share that paper with you, but since it is a working paper which is not published yet I would prefer to send in private. , this code provides the second stage Fama and Macbeth results, but as I check the first stage it only shows me â¦ (Dots) in the first process, why? Thanks. So basically I am running a regression cross sectionally on each period to get lambda and alpha. The first step involves estimation of N cross-sectional regressions and the second step involves T time-series averages of the coefficients of the N-cross-sectional regressions. Fama-MacBeth regression. The standard errors are adjusted for cross-sectional dependence, see Fama and MacBeth(1973) paper for more details. The following code will run cross-sectional regressions by year for all firms and report the means. Hi Sir, Second, for each time period t, run a cross-sectional regression: This yields an estimated lambda_t (price of risk) and alpha_t for each time period. Is it impossible to use newey when you have some gaps in the date variable? How is FM different? Third, construct estimates of unconditional lambda's and alpha's by averaging over time. In my dataset the independent variable ( for example the market excess return) has the same value for each Portfolio while in your case the independent variable has different value for each portfolio. Is the F value in asreg Y X, fmb by(time) defined as the time-series average of the F values from the cross-sectional regressions? 1.Â Arrange the data as panel data and use xtset command to tell Stata about it. Intuitively, if the price of risk and other variables are constant over time, then the two estimates will be the same. Does your theory suggest that? Regressing ERP on a constant, regression will omit the constant. This project investigates the under-pricing phenomenon of initial public offering (IPO) both in the short- and long-run. I have not been able to find articles concerning this issue so far. I am running in some trouble using asreg with the fmb option. As of now, if you look at the output of that is produced by first, the command uses the dummies seemingly random over time. Jerome Rebe The first step involves estimation of N cross-sectional regressions and the second step involves T time-series averages of the coefficients of the N-cross-sectional regressions. Will it impact my result? Journal of Political Economy, 81(3), 607-636. How is FM different? Or do you estimate one regression on each firm (even though some may be unbalanced, thus some periods may be missing both in the long time interval both also in consecutive periods), and then take the average of this coefficient for each year given the firm present in each period.
