This paper shows that dynamic inefficiency can occur in dynamic general equilibrium models with fully optimizing, infinitely-lived households even in a situation with underinvestment. We identify necessary conditions for such a possibility and illustrate it in a standard R&D-based growth model....

This paper addresses the limitations of Modern Money Theory (MMT) as a guide to development policy. We explore two central questions on this topic: whether MMT policies 1) ought to be implemented in low- and middle-income economies and 2) can be implemented. In relation to the first question, we...

Although there exists a vast literature on convergence and divergence of income levels across countries or regions at the aggregate level, there is only little work on convergence and/or diver- gence processes of productivity and wage levels at the more disaggregated industrial level. These are...

Although the mere observation of saving aggregates might have us believe differently, this article argues that Singapore's sustained high saving performance was far from extraordinary once the country's particular circumstances are econometrically controlled for. Singapore's saving performance...

The recycling problem is general, and is not confined to a multicurrency setting: whenever there are surplus and deficit units-that is, everywhere-adjustment in real terms can be either upward or downward. The question is, Which? An attempt is made to formulate the problem in terms of the...

Since the current recession began in December 2007, New Deal legislation and its effectiveness have been at the center of a lively debate in Washington. This paper emphasizes some key facts about two kinds of policy that were important during the Great Depression and have since become the focus...

This paper investigates private net saving in the US economy - divided into its principal components, households and (nonfinancial) corporate financial balances - and its impact on the GDP cycle from the 1980s to the present. Furthermore, we investigate whether the financial markets (stock...

This paper investigates the relationship between asset markets and business cycles with regard to the United States economy. We consider the Goldman Sachs approach (2003) developed to study the dynamics of financial balances. By means of a small econometric model we find that asset market...

This paper derives conditions for two key Keynesian propositions in a simple IS-LM model: (a) the paradox of thrift, and (b) the crowding-in of private investment expenditures by government expenditures. A linear specifcation of the model is then presented as a special case that can be used for...

We use a quantitative equilibrium model with houses, collateralized debt and foreign borrowing to study the impact of global imbalances on the U.S. economy in the 2000s. Our results suggest that the dynamics of foreign capital flows account for between one fourth and one third of the increase in...
