The term 'financialization' describes the phenomenon that commodity contracts are traded for purely financial reasons and not for motives rooted in the real economy. Recently, financialization has been made responsible for causing adverse welfare effects especially for low-income and low-wealth...

In this paper, we conduct an analysis of the implications of capital controls for financial stability. We study a financial transaction (Tobin) tax applicable to cross-border capital flows in a multi-good, multi-country dynamic equilibrium model with incomplete financial markets and...

In this paper we analyze an economy with two heterogeneous investors who both exhibit misspecified filtering models for the unobservable expected growth rate of the aggregated dividend. A key result of our analysis with respect to long-run investor survival is that there are degrees of model...

In this paper, we directly test the Modigliani-Miller theorem in the lab. Applying a general equilibrium approach and not allowing for arbitrage among firms with different capital structures, we are able to address this issue without making any assumptions about individuals' risk attitudes and...

We analyze the equilibrium in a two-tree (sector) economy with two regimes. The output of each tree is driven by a jump-diffusion process, and a downward jump in one sector of the economy can (but need not) trigger a shift to a regime where the likelihood of future jumps is generally higher....

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...

In this paper, we directly test the Modigliani-Miller theorem in the lab. Applying a general equilibrium approach and not allowing for arbitrage among firms with different capital structures, we are able to address this issue without making any assumptions about individuals' risk attitudes and...

There has been a considerable debate whether disaster models like Barro (2006) can rationalize the equity premium puzzle. This is because empirically disasters are not single extreme events, but tend to be long-lasting periods in which moderate negative consumption growth realizations cluster....

We develop a model that reproduces the average return and volatility spread between sin and non-sin stocks. Our investors do not necessarily boycott sin companies. Rather, they are open to invest in any company while trading off dividends against ethicalness. We show that when dividends and...

Most financial asset pricing models assume frictionless, competitive markets that imply the absence of arbitrage opportunities. Given the absence of arbitrage opportunities and complete asset markets, there exists a unique martingale measure that implies martingale pricing formulae and...
