This paper is a first step toward a more fundamental theory of political economy outcomes. We start from the fundamentals of the economy, given by preferences and technology; further, we specify all available technologies for the control of resources — such as armed forces or bribing. We model...

Globalization increasingly involves less-developed countries (LDCs), i.e., economies which usually suffer from severe imperfections in their financial systems. Taking these imperfections seriously, we analyze how credit frictions affect the distributive impact of trade liberalizations. We find...

This essay examines the implications of openness to trade, capital mobility, and exchange rate exibility for the fiscal multiplier. It presents a New Open Economy Macroeconomics model which is extended with the formation of 'deep habits' by individual households. Hereby, an inter-temporal...

This paper analyzes the dynamic effects of a fiscal policy shock and its transmission mechanism in a small open economy and compares the responses under different specifications of the utility function. The traditional Mundell-Flemming model tells that fiscal policy is more effective under a peg...

This paper proposes a method for the welfare analysis of pay-as-you-go social security systems. We derive a formula for the welfare consequences of a permanent marginal change in the payroll tax rate that is valid under weak assumptions about the deep structure of the economy. Our approach...

This paper proposes a new method for welfare analysis of unfunded social security systems. Based on an overlapping generations model with endogenous labor supply, we derive a formula for the evaluation of existing pay-as-you-go social security systems that depends on impulse response functions...

When the transmission channel between savers and borrowing firms is disturbed, firms may find themselves borrowing-constrained. I study the optimal fiscal policy response to a tightening borrowing constraint in a simple two-period model. I find that it is not optimal to subsidize firms, although...

We propose a theory of tax centralization in politico-economic equilibrium. Taxation has dynamic general equilibrium implications which are rationally internalized at the federal, but not at the regional level. The political support for taxation therefore differs across levels of government....

Optimal monetary and fiscal policy are jointly analyzed in a heterogeneous two-agents New Keynesian environment, where fiscal policy is modeled in the form of lump-sum transfers set by the government. The main result is that transfer policy does not serve as a substitute for forward guidance -...
