We study the effects of a change in some exogenous variable (the fixed cost or a parameter in the payoff functions) on the strategies played in a Symmetric Cournot Equilibrium with Free Entry (SCEFE). We also show that any observation on prices, profits and number of firms is compatible with the...

The authors examine a variant of the uncapacitated lot-sizing model of Wagner-Within involving sales instead of fixed demands, and lower bounds on stocks. Two extended formulations are presented, as well as a dynamic programming algorithm and a complete description of the convex hull of solutions.

In a framework with an upstream monopoly and downstream duopoly, we analyze the impact of vertical integration when downstream firms have convex costs.

In this paper we offer the Gibbs sampler as an alternative estimator to the the GMM procedure used by berry, Levinsohn, and Pakes (1995) (henceforth BLP) in their equilibrium differentiated product market analysis of the automobile industry.

The interaction of various methods of mitigating economic and international double taxation of corporate source income is studied within a standard neoclassical model of firm behavior. The main purpose is to determine to what extent methods effective in mitigating economic double taxation in a...

We test for the presence of long memory in daily stock returns and their squares using a robust semiparametric procedure. Spurious results can be produced by nonstationarity and aggregation.

Most hypotheses in binary response models are composite. The null hypothesis is usually that one or more slope coefficients are zero. Typically, the sequence of alternatives of interest is one in which the slope coefficients are increasing in absolute value. In this papar, we prove that the...

The optimal minimum distance (OMD) estimator for models of covariance structure is asymptotically efficient but has much worse finite-sample properties than does the equally-weighted minimum distance (EWMD) estimator. This paper shows how the bootstrap can be used to improve the finite-sample...

This paper makes two contributions to the literature on equilibrium search models. We cast the problem of determining the number of productivity types into a search for modes of the wage distribution and we use recent techniques of mode hunting to estimate the number and location of these modes.
