The Schumpeterian view on Business cycles treats recessions as a cleansing mechanism and a state where firms can regroup and innovate. Firms need to access finance externally in order to compensate declining cash flow in recessions. Due to financial frictions, the literature proposes that firms...

In this paper we solve an optimal stopping problem with an infinite time horizon, when the state variable follows a jump-diffusion. Under certain conditions our solution can be interpreted as the price of an American perpetual put option, when the underlying asset follows this type of process. <p>...</p>

This paper presents a unified framework for examining the general equilibrium effects of transactions costs and trading constraints on security market trades and prices. The model uses a discrete time/state framework and Kuhn-Tucker theory to characterize the optimal decisions of consumers and...

Was the increase in income inequality in the US due to permanent shocks or merely to an increase in the variance of transitory shocks? The implications for consumption and welfare depend crucially on the answer to this question. We use CEX repeated cross-section data on consumption and income to...

This paper first extends the canonical General Equilibrium with Incomplete Markets (GEI) model with money and default to allow for competitive banking and financial instability. Second, it introduces capital requirements for the banking sector to assess the short and medium term macroeconomic...

We provide a geometric test of whether a general equilibrium incomplete markets (GEI) economy has Hart points---points at which the rank of the securities payoff matrix drops. Condition (H) says that, at each nonterminal node, there is an affine set (of appropriate dimension) that intersects all...

The paper analyzes the process of market selection of investment strategies in an incomplete market of short-lived assets. In the model understudy, asset payoffs depend on exogenous random factors. Market participants use dynamic investment strategies taking account of available information...

This paper considers a standard general equilibrium model with incomplete markets, which is extended to incorporate durable goods and the possibility of default, following Dubey, Geanakpolos and Shubik (1990) and Geanakoplos and Zame (1998). In such a model asset markets will not be active...

An economy with two dates is considered, one state at the first date and a finite number of states at the last date. Shareholders determine production plans by voting — one share, one vote — and at ?-majority stable stock market equilibria, alternative production plans are supported by at...

This paper shows that a stock market is evolutionary stable if and only if stocks are evaluated by expected relative dividends. Any other market can be invaded by portfolio rules that will gain market wealth and hence change the valuation. In the model the valuation of assets is given by the...
