We develop an infinite time horizon, continuous time model of portfolio choice and consumption allocation for an investor seeking to maximize the expected utility of his life-time consumption. In this model, the investor is endowed with capital that can be invested in long-lived capital assets...

Investment behavior is analyzed using a dynamic portfolio model including off-farm income. The correlation structure of off-farm income and asset returns and the ratio of off-farm income to wealth is shown to affect portfolio choice. Empirical analysis indicates that off-farm income tends to...

This paper studies the impact of enhanced transparency on risk sharing opportunities in the foreign exchange market and the associated implications for ex ante welfare. Transparency is measured in this model by the informational content of publicly observable signals about exchange rate...

This paper develops a general equilibrium model for a representative agent, production economy with stochastic internal habit formation. The model describes a scale-independent economy, with a unique stochastic investment opportunity set. Local correlation between the stochastic interest rate...

Markowitz and Sharpe won the Nobel Prize in Economics for the development of Mean-Variance (M-V) analysis and the Capital Asset Pricing Model (CAPM). Kahneman won the Nobel Prize in Economics for the development of Prospect Theory. In deriving the CAPM, Sharpe, Lintner and Mossin assume expected...

In a setting where the lender and the borrower have heterogeneous beliefs about the likelihood of a disastrous shock to the borrower's economy, we revisit the debt contract proposed by Barro (2006). We find that a higher belief by the lender compared to the borrower can lead to countercyclical...

In this paper we provide necessary and sufficient conditions for the excess demand function of a pure exchange economy to be globally invertible so that there is a unique equilibrium. Indeed, we show that an excess demand function is globally invertible if and only if its Jacobian never vanishes...

Smart Contracts (SCs) are usually defined as contracts that are instantiated in computer-executable code that automatically executes all or parts of an agreement with the assistance of block-chain’s distributed trust technology. This is principally a technical description and results in an...

We propose a 2-country asset-pricing model where agents' preferences change endogenously as a function of the popularity of internationally traded goods. We determine the effect of the time-variation of preferences on equity markets, consumption and portfolio choices. When agents are more...

We study the effects of market incompleteness on speculation, investor survival, and asset pricing moments, when investors disagree about the likelihood of jumps and have recursive preferences. We consider two models. In a model with jumps in aggregate consumption, incompleteness barely matters,...
