This paper calibrates the production functions of 176 countries to fit 2003 data and examines the capital flows that emerge, when labor forces change according to the 2007 UN population projections. It finds that demographic factors are no help in correcting today's global imbalances; that...

We explore the underlying determinants of the macroeconomic effects of fiscal policy and tax and social security reform using the Global Fiscal Model (GFM). We show that the planning horizon of consumers, access to financial markets, and the elasticity of labor supply, as well as the...

We question the conventional view that it is optimal for government to maintain a stable level of spending out of oil wealth. We compare this conventional policy recommendation with one where government spends all of its oil revenues upfront, at the same rate as oil is extracted. Using a...

This paper uses the standard one-sector neoclassical growth model to investigate why China's consumption has been low and investment high. It finds that the low cost of capital has been quantitatively an important factor. Theory predicts that the price of capital may have been significantly...

The paper develops a tractable way to incorporate the micro structure of dual models of international trade into a standard class of dynamic open-economy macro models. In the process, it develops the concept of a dynamic factor price equalization set and an integrated intertemporal equilibrium....

The Korean authorities having taken decisive and proactive fiscal measures to help stem the fallout from the current global economic and financial crisis, with the size of the fiscal stimulus well-above the average response of other G20 economies. In this context, a key question is how effective...

Using representative and consistent microdata from the German Socio-Economic Panel Study (SOEP) from 1985-2007, we illustrate that capital income (CI = return on financial investments) and imputed rent (IR = return on investments in owner-occupied housing) have become increasingly important...

This paper analyzes the efficient taxation of oil and capital income in an oil-dependent infinite-lived economy facing perfect capital mobility. Two cases are examined: one with product market imperfections and free tax choice, one with perfect competition and tax restrictions. The optimal tax...

This paper gauges the key determinants of China's private consumption in relation to GDP using data on the Chinese economy and evidence from other countries' experiences. The results suggest there is nothing "special" about consumption in China. Rather, the challenge is to explain why the...

This paper discusses the degree of intertemporal comparability of national estimates of income inequality when data are based on income tax records. The problem of comparability is particular crucial when major tax reforms have taken place and pre- and post-reform income data are used as basis...
