Research by Chirinko (1982,1985,1987) makes a convincing argument that Q theory is unlikely to provide a satisfactory investment model. However, Klock Thies, and Baum (1991) show that Q is commonly mismeasured. The finding is applicable to Chirinko’s empirical research and raises the question...

By 1989 the Michigan Panel Study on Income Dynamics (PSID) had experienced approximately 50 percent sample loss from cumulative attrition from its initial 1968 membership. We study the effect of this attrition on the unconditional distributions of several socioeconomic variables and on the...

This tutorial will discuss a number of elementary Stata programming constructs and discuss how they may be used to automate and robustify common data manipulation, estimation and graphics tasks. Those used to the syntax of other statistical packages or programming languages must adopt a...

Using comparable micro-level data from three countries, we ask what type of person works in the informal sector and whether informal workers earn lower wages than observationally equivalent workers in the formal sector. The characteristics of informal workers are similar across countries....

This paper provides estimators of discrete choice models, including binary, ordered, and multinomial response (choice) models. The estimators closely resemble ordinary and two stage least squares. The distribution of the model's latent variable error is unknown and may be related to the...

This paper proposes a method for comparing and combining conditional quantile forecasts in an out-of-sample framework. We construct a Conditional Quantile Forecast Encompassing (CQFE) test as a Wald-type test of superior predictive ability. Rejection of CQFE provides a basis for combination of...

The objective of this paper is to investigate if and how capital adjustment departs from the smooth pattern implied by standard model based on convex adjustment costs. Using Norwegian micro data, we start by documenting various aspects of the distribution of investment rates. We then present two...

In this paper, we compare the patterns of labor force withdrawal of older workers in seven OECD countries. We find wide variation in retirement patterns and recent trends. In Sweden and the United States, for example, it is relatively common for workers to combine retirement benefits and...

This paper investigates the link between the optimal level of non-financial firms' liquid assets and uncertainty. We develop a partial equilibrium model of precautionary demand for liquid assets showing that firms alter their liquidity ratio in response to changes in either macroeconomic or...

All countries would agree to immediate global free trade if countries were compensated for any terms-of-trade losses with transfers from countries whose terms-of-trade improve, and if customs unions were required to have no effects on non-member countries. Global free trade with transfers is in...
