Última A Small-Sample Estimator for the Sample-Selection Model AgEcon Golan, Amos; Moretti, Enrico; Perloff, Jeffrey M.. A semiparametric estimator for evaluating the parameters of data generated under a sample selection process is developed. This estimator is based on the generalized maximum entropy estimator and performs well for small and ill-posed samples. Theoretical and sampling comparisons with parametric and semiparametric estimators are given. This method and standard ones are applied to three small-sample empirical applications of the wage-participation model for female teenage heads of households, immigrants, and Native Americans.

Ano: 2001 URL: http://purl.umn.edu/25047 An information based sample-selection estimation model of agricultural workers' choice between piece-rate and hourly work AgEcon Golan, Amos; Moretti, Enrico; Perloff, Jeffrey M.. This paper presents a new generalized maximum entropy (GME) approach to estimation of sample-selection models with small data sets, such as are found in many empirical agricultural economic analysis. For small samples, the GME approach produces more stable estimates and has smaller mean square error measures than other well-known estimators such as ordinary least squares, Heckman's two-step method, full-information maximum likelihood, and Ahn and Powell's method. The technique is used to analyze whether hired agricultural workers will work in piece-rate or time-rate jobs and to compare female-male wage differentials for both types of jobs.

Ano: 1998 URL: http://purl.umn.edu/47285 Effects of Government Policies on Income Distribution and Welfare AgEcon Wu, Ximing; Perloff, Jeffrey M.; Golan, Amos. A variety of parametric and semiparametric models produce qualitatively similar estimates of government policies' effects on income distribution and welfare (as measured by the Gini, standard deviation of logarithms, relative mean deviation, coefficient of variation, and various Atkinson indexes). Taxes and the Earned Income Tax Credit are an effective way to redistribute income to the poor and raise welfare. The minimum wage lowers welfare. Social insurance programs have little effect except for Supplemental Security Income, which raises welfare. Transfer programs (AFDC/TANF and food stamps) either have no statistically significant effect or lower welfare.

Ano: 2002 URL: http://purl.umn.edu/25031 ESTIMATING A MIXED STRATEGY EMPLOYING MAXIMUM ENTROPY AgEcon Golan, Amos; Karp, Larry S.; Perloff, Jeffrey M.. Generalized maximum entropy may be used to estimate mixed strategies subject to restrictions from game theory. This method avoids distributional assumptions and is consistent and efficient. We use this method to estimate the mixed strategies of duopolistic airlines. Tipo: Working or Discussion Paper Palavras-chave: Research Methods/ Statistical Methods.

Ano: 1997 URL: http://purl.umn.edu/25057 ESTIMATING THE SIZE DISTRIBUTION OF FIRMS USING GOVERNMENT SUMMARY STATISTICS AgEcon Golan, Amos; Judge, George G.; Perloff, Jeffrey M.. Using a maximum entropy technique, we estimate the market shares of each firm in an industry using the available government summary statistics such as the four-firm concentration ratio (C4) and the Herfindahl-Hirschmann Index (HHI). We show that our technique is very effective in estimating the distribution of market shares in 20 industries. Our results provide support for the recent practice of using HHI rather than C4 as the key explanatory variable in many market power studies, if only one measure is to be used.

Ano: 2004 URL: http://purl.umn.edu/25125 Superior Forecasts of the U.S. Unemployment Rate Using a Nonparametric Method AgEcon Golan, Amos; Perloff, Jeffrey M.. We use a nonlinear, nonparametric method to forecast the unemployment rates. We compare these forecasts to several linear and nonlinear parametric methods based on the work of Montgomery et al. (1998) and Carruth et al. (1998). Our main result is that, due to the nonlinearity in the data generating process, the nonparametric method outperforms many other wellknown models, even when these models use more information. This result holds for forecasts based on quarterly and on monthly data.

Ano: 2002 URL: http://purl.umn.edu/25060 Welfare Effects of Minimum Wage and Other Government Policies AgEcon Golan, Amos; Perloff, Jeffrey M.; Wu, Ximing. The minimum wage, unlike most government transfer programs, lowered welfare in the 1980s and 1990s as measured by all commonly used welfare or inequality measures, including various Atkinson indexes, the Gini index, standard deviation of logarithms, and others. The effects of most government programs, macroeconomic variables, and aggregate demographic characteristics were qualitatively the same for all the inequality measures.
