The post-1983 moderation coincided with an ahistorical divergence in the money aggregate growth and velocity volatilities away from the downward trending GDP and inflation volatilities. Using an en dogenous growth monetary DSGE model, with micro-based banking production, enables a contrasting...

The fall in US macroeconomic volatility from the mid-1980s coincided with a strong rise in asset prices. Recently, this rise, and the crash that followed, have been attributed to overconfidence in a benign macroeconomic environment of low volatility. This paper introduces learning about the...

The aim of this paper is to construct theoretical models which help to shed light on the recent criticisms of volatile investment flows. We do not make any empirical attempt to establish the existence or gauge the importance of the adverse effects of volatile investment flows nor do we make any...

In this paper, we derive closed-form solutions for a variety of prices for financial assets in an RBC economy. The equations are based on a loglinear solution of the RBC model and allow a clearer understanding of the determination of risk premia in models with production. E.g., we show that risk...

We use portfolio theory to quantify the efficiency of state-level sectoral patterns of production in the United States. On the basis of observed growth in sectoral value-added output, we calculate for each state the efficient frontier for investments in the real economy. We study how rapidly...

In this paper, we consider economies with (possibly endogenous) solvency constraints under uncertainty. Constrained inefficiency corresponds to a feasible redistribution yielding a welfare improvement beginning from every contingency reached by the economy. A sort of Cass Criterion (Cass (1972))...

In the context of an overlapping generations model, we show that liquidity constraints on households: (i) raise the saving rate; (ii) strengthen the effect of growth on saving; and (iii) increase the growth rate if productivity growth is endogenous. These propositions are supported by...

Risk premia in the consumption capital asset pricing model depend on preferences and dividends. We develop a decomposition which allows for the separate treatment of both components. We show that preferences alone determine the risk-return trade-off measured by the Sharpe-ratio. In general, the...

This paper offers a theory of development which links the degree of market incompleteness to capital accumulation and growth. At early stages of development, the presence of indivisible projects limits the degree of risk-spreading (diversification) that the economy can achieve. The desire to...

This paper evaluates models with idiosyncratic consumption risk using Hansen and Jagannathan’s (1991) volatility bounds. It is shown that idiosyncratic risk does not change the volatility bounds at all when consumers have constant relative risk aversion (CRRA) preferences and the distribution...
