In this paper, the authors investigate the sensitivity of investment to the availability of internal funds using the hierarchy of finance approach to corporate finance. They characterize the empirical implications of this approach for dynamic investment models and test these implications using...

This paper shows that with (partial) irreversibility higher uncertainty reduces the "responsiveness "of investment to demand shocks. Uncertainty increases real option values making firms more cautious when investing or disinvesting. This is confirmed both numerically for a model with a rich mix...

This paper presents specification tests that are applicable after estimating a dynamic model from panel data by the generalized method of moments, and studies the practical performance of these procedures using both generated and real data. The authors' generalized method of moments estimator...

In this paper, we use an economic model to analyse data from a major randomized social experiment, namely PROGRESA in Mexico, and to evaluate its impact on school participation. We show the usefulness of using experimental data to estimate a structural economic model as well as the importance of...

This paper uses microeconomic data from the U.K. Family Expenditure Surveys (FES) and the General Household Surveys (GHS) to describe and explain changes in the distribution of male wages. Since the late 1970s wage inequality has risen very fast in the U.K., and this rise is characterized both...

The authors develop an empirical model of labor supply that is consistent with on-the-job search and that is identified and estimated by combining two data sets: the U.K. Family Expenditure Survey, which contains information on income and expenditure, and the U.K. Labour Force Survey, which has...

In this paper we study the sources of wage growth. We identify the contribution to such growth of general, sector specific and firm specific human capital. Our results are interpretable within the context of a model where the returns to human capital may be heterogeneous and where firms may...

We present identification and estimation results for the "collective" model of labour supply in which there are discrete choices, censoring of hours, and non-participation in employment. We derive the collective restrictions on labour supply functions and contrast them with restrictions implied...

The purpose of this paper is to estimate the parameters of household preferences that determine the allocation of goods within the period and over the life cycle, using micro data. In doing so, the authors are able to identify important effects of demographics, labor market status, and other...
