This paper investigates the trend of the wage inequality and the metropolitan wage premium in the United States during the 1980s. Two distinct sets of literature documented that the wage inequality between skilled and unskilled workers and the metropolitan wage premium have risen significantly...

Arguably the fundamental problem faced by employers is how to elicit effort from employees. Most models suggest that employers meet this challenge by monitoring employees carefully to prevent shirking. But there is another option that relies on heterogeneity across employees, and that is to...

We consider estimation and inference of parameters in discrete games allowing for multiple equilibria, without using an equilibrium selection rule. We do a set inference while a game model can contain infinite dimensional parameters. Examples can include signaling games with discrete types where...

Rapid global technological changes have resulted in an increase in the demand for workers with higher education. Not only is this trend identified in OECD countries, but it is also observable in most East Asian countries. In response to the intensification of competition caused by the emergence...

The paper studies the effects of the changing age and education composition of the labour force on productivity growth in Singapore. The quality change of workers from aging and education is measured through a quality index. Quality change through education is the key driving force for the...

The purpose of this study is to reexamine two empirical regularities in the Japanese labor market : the constant labor share and Okun's law. The former law relates to the price of labor in the labor market while the latter is a quantity law; they represent suitable benchmarks for judging the...

This article derives a simple method for projecting pension deficit as percent of GDP in future years based on commonly available population forecasting and a few predictable economic and policy variables. Compared with the classic basic equilibrium equation of pension funds, our new formula...

This paper studies an econometric modeling of a signaling game with two players where one player has one of two types. In particular, we develop an estimation strategy that identies the payos structure and the distribution of types from data of observed actions. We can achieve uniqueness of...

In this study we investigate the causes of low secondary school enrollment in Indonesia despite near universal primary school attendance. We then find that attrition during the transition between primary and junior secondary education levels is the main cause. We investigate the causes of...

This paper studies an alternative bias correction for the M-estimator, which is obtained by correcting the moment equation in the spirit of Firth (1993). In particular, this paper compares the stochastic expansions of the analytically bias-corrected estimator and the alternative estimator and...
