T he welfare cost of inflation in a new Keynesian model has been studied in this article. Nominal prices and wages are subjected to Rotenberg's adjustments in the benchmark model. In addition, this study uses the CIA model to compare the welfare cost of seigniorage tax and consumption tax. The model is calibrated for the Iranian economy and the results of the calibration are as follow...

We study the representative consumer’s risk attitude and efficient risk-sharing rules in a singleperiod, single-good economy in which consumers have homogeneous probabilistic beliefs but heterogeneous risk attitudes. We prove that if all consumers have convex absolute risk tolerance, so must the representative consumer. We also identify a relationship between the curvature of an individual cons...

We present a decomposition approach for integrated assessment modeling of climate policy based on a linear approximation of the climate system. Our objective is to demonstrate the usefulness of decomposition for integrated assessment models posed in a complementarity format. First, the complementarity formulation cum decomposition permits a precise representation of post-terminal damages thereb...

UK regional policy has been advocated as a means of reducing regional disparities and stimulating national growth. However, there is limited understanding of the interregional and national effects of such a policy. This paper uses an interregional computable general equilibrium model to identify the national impact of a policy-induced regional demand shock under alternative labour market closur...

We analyse how the welfare state, i.e., social insurance that works through redistributive taxation, should respond to increases in risks and to increases in the cost of operating the welfare state. With respect to risks, we distinguish between risks that can be insured and such that cannot (background risks). Insurable risks can be reduced by costly individual selfinsurance and by costly socia...

We extend a standard overlapping-generations general-equilibrium model with idiosyncratic working ability shocks to design the optimal social security pension system. There are two main features in our approach. First, we keep track of individual social security wealth explicitly so that we can evaluate a wide range of policies, including “private accounts,” seamlessly. Second, we express our s...

This paper argues that barriers affect both the beginning date and the subsequent pace of modern growth, and taking into account this fact enriches our knowledge of cross-country income differences. The model matches the observed inverted U-shape of cross-country income differences, which implies that a substantial fraction of current income differences is transitional. Hence, the model require...

This paper reviews Bolivia’s economic and social development over the period 198599, and investigates the country’s future prospects for pro-poor growth using a Computable General Equilibrium (CGE) model. Model simulations show that under optimistic assumptions the growth and poverty goals envisaged in the Bolivian poverty reduction strategy may be achieved, but that performance will fall short...

We derive the optimal crowdfunding contract of a financially constrained monopolist and analyze its implications for production, investment and welfare. Crowdfunding contracts may serve as a price-discrimination mechanism, forcing pivotal consumers to pay a premium above the future spot price, thus increasing profits. When raising funds is costly, entrepreneurs balance the benefits from price d...

This paper analyses how different types of access regulation to next generation networks affect investments and consumer welfare. The model consists of an investment stage with uncertain returns and subsequent quantity competition. The access price is a function of investment costs and the regulatory regime. A regime with fully distributed costs or regulatory holiday induces highest investments...
