This paper provides a consistent and asymptotically normal estimator for the intercept of a semiparametrically estimated sample selection model. The estimator uses a decreasingly small fraction of all observations as the sample size goes to infinity, as in Heckman (1990). In the semiparametrics...

In the classical general equilibrium model, agents keep all their promises, every good is traded, and competition prevents any agent from earning superior returns on investments in financial markets. In this paper I introduce the age-old problem of broken promises into the general equilibrium...

Between about the mid 1960s and the late 1970s there was a remarkable rise in the labor force participation of women and then a leveling off that has persisted through the mid 1990s. This paper attempts to explain the labor force participation of women 20-24 over this period. A "relative income"...

Within the last five years, Canada, Sweden and New Zealand have joined the ranks of the United Kingdom and other countries in issuing government bonds that are indexed to inflation. Some observers of the experience in these countries have argued that the United States should follow suit. This...

A questionnaire survey was conducted to explore how people think about inflation, and what real problems they see it as causing. With results from 677 people, comparisons were made among people in the U.S., Germany, and Brazil, between young and old, and between economists and non-economists....

The results in this paper, based on estimating and testing price equations for 30 countries, do not support the standard view of the long-run relationship between unemployment and inflation. They overwhelmingly reject the dynamics implied by the standard view. Wage equations are also estimated...

We present a model of a financial market which unifies the capital-asset-pricing model (CAPM) of Sharpe-Lintner, and the arbitrage pricing theory (APT) of Ross. The model is based on a recent theory of hyperfinite processes, and it uncovers asset pricing phenomena which cannot be treated by...

In this paper we propose a modelling approach for labor supply and consumption decisions that is firmly grounded within a utility maximizing framework and allows for a role of such institutional constraints as limited access to borrowing and involuntary unemployment. We report estimations for a...

We present a finite system of polynomial inequalities in unobservable variables and market data that observations on market prices, individual incomes and aggregate endowments must satisfy to be consistent with the equilibrium behavior of some pure trade economy. Quantifier elimination is used...

We survey recent theoretical research on the effects of short-term share-price based marginal incentive schemes. Such schemes can induce inefficient managerial behaviour in both hidden action and hidden type contexts. These problems arise from informational asymmetries: managers take actions to...
