We incorporate the consumption-ability relationship of static "efficiency wage" models into a dynamic general equilibrium model. We show that for many aggregate land stocks, there is a continuum of unemployment rates which could persist indefinitely as part of a stationary equilibrium. For many of these aggregate land stocks, both unemployment and full employment are distrinct possibilities. Broadly speaking, more unemployment corresponds to more undernourishment and more inequality in land distribution. Thus our results suggest that the market mechanism is less efficacious than land reform in reducing unemployment and undernourishment.

Creator: Grossman, Gene M. and Helpman, Elhanan. Series: International perspectives on debt, growth, and business cycles Abstract:
We construct a model of the product cycle featuring endogenous innovation and endogenous technology transfer. Competitive entrepreneurs in the North expend resources to bring out new products whenever expected present discounted value of future oligopoly profits exceeds current product development costs. Each Northern oligopolist continuously faces the risk that its product will be copied by a Southern imitator, at which time its profit stream will come to an end. In the South, competitive entrepreneurs may devote resources to learning the production processes that have been developed in the North. There too, costs (of reverse engineering) must be covered by a stream of operating profits. We study the determinants of the long-run rate of growth of the world economy, and the long-run rate of technological diffusion. We also provide an analysis of the effects of exogenous events and of public policy on relative wage rates in the two regions.

Creator: Mendoza, Enrique G., 1963- and Smith, Katherine A. Series: Advances in dynamic economics Abstract:
"Sudden Stops " experienced during emerging markets crises are characterized by large reversals of capital inflows and the current account, deep recessions, and collapses in asset prices. This paper proposes an open-economy equilibrium asset pricing model in which financial frictions cause Sudden Stops. Margin requirements impose a collateral constraint on foreign borrowing by domestic agents and trading costs distort asset trading by foreign securities firms. At equilibrium, margin constraints may or may not bind depending on portfolio decisions and equilibrium asset prices. If margin constraints do not bind, productivity shocks cause a moderate fall in consumption and a widening current account deficit. If debt is high relative to asset holdings, the same productivity shocks trigger margin calls forcing domestic agents to fire-sell equity to foreign traders. This sets off a Fisherian asset-price deflation and subsequent rounds of margin calls. A current account reversal and a collapse in consumption occur when equity sales cannot prevent a sharp rise in net foreign assets.
