Two results characterize previous studies of optimal capital income taxation: (i) In order to avoid distorting capital accumulation incentives the ex ante capital tax rate should be set to zero in the long run and ii) by varying the ex post capital tax rate governments may be able to insulate...

This paper describes the behavior of tax policies under incomplete financial markets. The government finances a stochastic stream of expenditures by collecting the capital income and the labor income taxes, and issuing a one-period bond which pays state-contingent returns. We show that putting...

We connect two major strands of the recent monetary policy literature, i) the search for well microfounded optimising models consistent with macroeconomic data, especially persistence in inflation, and ii) the wealth of newly available microeconomic data on price changing behaviour from the...

We provide analytical and empirical underpinnings for the notion that the financial fragility of the aggregate economy depends on the balance sheet conditions of the corporate sector. First, we obtain time-varying semiparametric estimates of the relationship between the debt-equity ratio and the...

The relationship between income inequality and economic growth is re-examined using a semiparametric, dynamic panel data model. Significant empirical evidence is uncovered supporting the theory that the relationship between these variables is nonlinear. Additionally, the evidence also supports...

Empirical literature on investment and output dynamics is characterized by two robust stylized facts at the macro level. First, investment is considerably more volatile than output. Second, fluctuations of output and investment are highly synchronized. Furthermore, at the micro level, firm...

There are two basic tools to analyse fundamental issues in dynamical macroeconomics. One of them is a model of optimal growth describing savings behaviour. The second one is the Solow-Swan model with a constant aggregate propensity to save out of income. A steady state of the dynamical economic...
