Observers have often characterized asset markets as being subject to periods of tranquility and periods of turbulence. Until recently, however, researchers were unable to produce closed-form asset pricing formulas in a model environment of time-varying risk. Some work by Abel provided us with...

During the period leading up to the global financial crisis many asset classes registered rapid price increases. This coincided with a significant rise in global liquidity. This paper attempts to determine the extent to which the rise in asset prices was influenced by developments in global...

This paper examines the evidence for the common assertion that the volatility of emerging stock markets has increased as a result of the liberalization of markets. A range of measures suggests that there has been no generalized increase in volatility in recent years; indeed, it appears that...

Since the mid-1970s, there has been considerable research on the macroeconomic consequences of wage indexation. Nonetheless, until recently, this research had not explicitly explored the implications of contracts that index wages to lagged inflation, the usual type of wage indexation observed in...

The aim of the paper is to shift the focus of famine analysis away from food supply towards the macroeconomic determinants of food entitlement—i.e., to the ability of individuals to purchase food. Towards this end, we develop a model to demonstrate how loose monetary and fiscal policies may...

In several recent articles, the Barro-Grossman model of general equilibrium under shortage has been modified to incorporate money demand and alternative retail sales mechanisms. This paper extends this work to allow for spillovers in deficit goods markets (modeled as feedback of black market...

This paper describes a computer program with which one can build macroeconomic models. It is possible to specify up to eighteen behavioral equations, each with between five and eleven independent variables. For certain variables, the user can decide whether they will be endogenous or exogenous....

We develop a New-Open-Economy-Macro model in which Ricardian equivalence does not hold because of (i) distortionary labor and corporate income taxation; (ii) limited asset market participation; and (iii) because the overlapping-generations structure results in a disconnect between current and...

We investigate the role of macroprudential policies in mitigating liquidity traps driven by deleveraging, using a simple Keynesian model. When constrained agents engage in deleveraging, the interest rate needs to fall to induce unconstrained agents to pick up the decline in aggregate demand....

We develop a simple semistructural model for the Rwandan economy to better understand the monetary policy transmission mechanism. A key feature of the model is the introduction of a modified uncovered interest parity condition to capture key structural features of Rwanda’s economy and policy...
