We study optimal government spending in a business cycle model with labor income taxes and unemployment due to hiring costs. Labor market frictions raise the optimal steady state ratio of government spending to private consumption. The labor tax rate is higher since profits are taxed that arise...

This paper undertakes a normative investigation of the quantitative properties of optimal tax smoothing in a business cycle model with state contingent debt, capital-skill complementarity and endogenous skill acquisition under technology and public expenditure shocks. We find that skilled and...

The aim of this paper is to quantify the role of formal-sector institutions in shaping the demand for human capital and the level of informality. We propose a firm dynamics model where firms face capital market imperfections and costs of operating in the formal sector. Formal firms have a larger...

We extend an open economy Ramsey model to include the technology gap to the world technology frontier. The setting is a middle income country with productivity growth driven by technology adoption and foreign capital goods stimulating spillover and catching up. The interaction of technology...

We propose a simple and powerful numerical algorithm to compute the transition process in continuous-time dynamic equilibrium models with rare events. In this paper we transform the dynamic system of stochastic differential equations into a system of functional differential equations of the...

Optimal control of dynamic econometric models has a wide variety of applications including economic policy relevant issues. There are several algorithms extending the basic case of a linear-quadratic optimization and taking nonlinearity and stochastics into account, but being still limited in a...

We construct a dynamic general equilibrium model of tax evasion where agents choose to report some of their income. Unreported income requires using a payment method that avoids recordkeeping in some markets—cash. Trade using cash to avoid taxes is the ‘shadow economy’ in our model. We...

We study the effect of a declining labor force on the incentives to engage in labor-saving technical change and ask how this effect is influenced by institutional characteristics of the pension scheme. When labor is scarcer it becomes more expensive and innovation investments that increase labor...

Empirical evidence has shown that exporters are more capital intensive than non-exporters. Based on this evidence, I construct a two-factor general equilibrium model with firm heterogeneity in factor intensities, monopolistic competition, scale economies and international trade. This setting can...

We present a model of structural change which, distinctively, sub-divides services (S) into ‘Progressive Services’ (PS) and ‘Asymptotically Stagnant Services’ (AS), to better reflect the advent of the New Economy. A manufacturing (M) sector is also included, and non-homothetic...
