The relative risk aversion (RRA) coefficient of a household whose consumption is close to the subsistence level may be very high. For example, if consumption is exactly at the subsistence level, the household may not be willing to bear any risk. If this is the case, then the RRA coefficient must...

This paper studies multiunit common value auctions with informed and less informed bidders. We show that bidders with less information can bid very aggressively and do surprisingly well in terms of probability of winning and expected revenue. We also show that the degree of aggressiveness and...

The costs of involuntary job loss are an object of substantial research and policy interest. We consider the measurement of the costs of job displacement with household expenditure data. We explicitly derive a "difference-in-difference" estimator from a structural life cycle model. This exercise...

We consider to what extent the empirical failings of the Q model of investment can be attributed to the assumption that stock market valuations accurately measure the present value of future net distributions to shareholders. We characterise the implications of different types of measurement...

We investigate the welfare implications of eliminating a proportional capital income tax for a model economy in which heterogeneous households face labor income risk and trade only one asset. Labor taxes rises at the time of the reform to maintain long run budget balance. Our stochastic process...

While the classical framework has a rich set of limited information procedures such as GMM and other related methods, the situation is not so in the Bayesian framework. We develop a limited information procedure in the Bayesian framework that does not require the knowledge of the likelihood...

Explaining procyclical productivity is crucial for any theory of the business cycle. Recent contributions have focused on the dynamic implications of persistent aggregate fluctuations on sectoral productivity. Given a permanent innovation in aggregate output, variations of labor (or capital)...

The aim of this paper is to provide empirically testable predictions regarding the relationship between market size and concentration. In the first part of the paper, a model of endogenous horizontal mergers is investigated. It is shown that concentrated outcomes can not be supported in a free...

In the context of multivariate regression (MLR) and simultaneous equations (SE), it is well known that commonly employed asymptotic test criteria are seriously biased towards over-rejection. In this paper, we propose exact likelihood based tests for possibly nonlinear hypotheses on the...

We consider the bootstrap unit root tests based on autoregressive integrated models, with or without deterministic time trends. A general methodology is developed to approximate asymptotic distributions for the models driven by integrated time series, and used to obtain asymptotic expansions for...
