ItemINTERNATIONAL TRADE AND INDUSTRIAL DYNAMICS(WILEY, 2009-08)In this article, industrial evolution is driven by endogenous technology choices of firms, generating a rich environment that includes the possibility of a dramatic shakeout. The likelihood, magnitude, and timing of this shakeout are characterized and depend not only on the size of an innovation but also on cost structure. In this setting, trade liberalization reduces the likelihood of a shakeout, resulting in more stable industrial structures. However, when shakeouts arise in global markets, the distribution of exits can vary widely across countries. Furthermore, conditions exist where a shakeout occurs in a closed economy but not in an open economy.

ItemComputing the Distributions of Economic Models via Simulation(Econometric Society, 2008-03-18)We study a Monte Carlo algorithm for computing marginal and stationary densities of stochastic models with the Markov property, establishing global asymptotic normality and OP(n–1/2) convergence. Asymptotic normality is used to derive error bounds in terms of the distribution of the norm deviation.

ItemResidual wage disparity and coordination unemployment(WILEY, 2006-08)How much of residual wage dispersion can be explained by an absence of coordination among firms? To answer, we construct a dynamic directed search model with identical workers where firms can create high‐ or low‐productivity jobs and are uncoordinated in their offers to workers, calibrated to the U.S. economy. Workers can exploit ex post opportunities once approached by firms, and can conduct on‐the‐job search. The stationary equilibrium wage distribution is hump‐shaped, skewed significantly to the right, and, with baseline parameters, generates residual dispersion statistics 75–90% of those found empirically. However, the model underestimates the average duration of unemployment.

ItemVertical integration in the presence of upstream competition(WILEY, 2005-09-01)We analyze vertical integration in the case of upstream competition andcompare outcomes to the case where upstream assets are owned by a single agent(i.e., upstream monopoly). In so doing, we make two contributions to themodelling of strategic vertical integration. First, we base industry structure –namely, the ownership of assets – firmly within the property rights approach tofirm boundaries. Second, we model the potential multilateral negotiations using afully specified, non-cooperative bargaining model designed to easily compareoutcomes achieved under upstream competition and monopoly. Given this, wedemonstrate that vertical integration can alter the joint payoff of integratingparties in ex post bargaining; however, this bargaining effect is stronger for firmsintegrating under upstream competition than upstream monopoly. We alsoconsider the potential for integration to internalize competitive externalities in amanner that cannot be achieved under non-integration; i.e., by favouring internalover external supply. We demonstrate that ex post monopolization is more likelyto occur when there is an upstream monopoly than when there is upstreamcompetition. Our general conclusion is that the simple intuition that the presenceof upstream competition can mitigate and reduce the incentives for sociallyundesirable vertical integration is misplaced and, depending upon the strength ofdownstream competition (i.e., product differentiation), the opposite could easilybe the case.
