In this paper we study a class of weighted estimands, which we define as parameters that can be expressed as weighted averages of the underlying heterogeneous treatment effects. The popular ordinary least squares (OLS), two-stage least squares (2SLS), and two-way fixed effects (TWFE) estimands...

This chapter presents an economic approach to character and personality traits with an application to the study of virtue. Economists interpret psychological traits, including character traits and virtue, as strategies that shape responses to situations (actions) determined by underlying...

Oaxaca and Ransom (1999) show that a detailed decomposition of the coefficients effect is destined to suffer from an identification problem since the detailed coefficients effect attributed to a dummy variable is not invariant to the choice of reference groups. It turns out that the...

We propose a simple methodology for decomposing differences in the first moment into characteristics and coefficients effects. This methodology provides a way to apply the Blinder-Oaxaca decomposition to a non-linear function for both aggregate and detailed decompositions.

In the empirical literature on labour supply, several static models are developed to incorporate constraints on working hours. These models do not address to what extent working hours are constrained within jobs, and to what extent working hours can be adjusted by means of changing employer. The...

In this paper, the role of the computer at the workplace will be examined in determining the wage structure in Germany. Following Krueger (1993) and using the German Socio- Economic Panel (GSOEP), cross-sectional wage regression results from 1997 and panel results from 1984-1997 are presented....

In this paper, the inter-industry wage structure in West Germany and USA is compared using the German Socio-Economic Panel (GSOEP), the German Mikrozensus (MZ), the American Panel Study of Income Dynamics (PSID) and the American Current Population Survey (CPS) from 1984 to 1996. Using a sample...

We analyze Engel curves for nuclear households in rural China. The sample includes more than 5000 nuclear families covering nineteen out of thirty Chinese provinces. We consider expenditures on food, also subdivided into several food subcategories such as cereals, or meat and fish, and other...

This paper joins discussions on normalized regression and decomposition equations in devising a simple and general algorithm for obtaining the normalized regression and applying it to the Oaxaca decomposition. This resolves the invariance problem in the detailed Oaxaca decomposition. An...

Theory predicts that the majoritarian electoral system should produce more targeted redistribution and lower politicians' rents than proportional representation. We test these predictions using micro data for the mixed-member Italian House of Representatives, which allow us to sidestep the...
