CLIMATE AND SCALE IN ECONOMIC GROWTH

This paper introduces new data on climatic conditions to empirical tests of growth theories. We find that, since 1960, temperate countries have converged towards high levels of income while tropical nations have converged towards various income levels associated with economic scale and the extent of the market. These results hold for a wide range of tests. A plausible explanation is that temperate regions' growth was assisted by their climate, perhaps historically for their transition out of agriculture into sectors whose productivity converges across countries, while tropical countries' growth is relatively more dependent on gains from specialization and trade.International Development,

Profit Sharing Between Governments and Multinationals in Natural Resource Extraction: Evidence From a Firm-Level Panel

The "fairness" of negotiations between countries and resource extracting firms is subject to many accusations and counter-accusations and may be argued, in many instances, to impact the subsequent economic benefit to a host country from extraction. This paper examines the role of host country governance on the share of government take from extraction revenue. We attempt to disentangle a number of competing hypotheses regarding the relationship between governance and government take using panel data for US resource extracting multinational corporations (MNCs) operating abroad from the Bureau of Economic Analysis of the US Department of Commerce over 1982-1999. Using fixed effects regression, we find a statistically significant positive impact of institutional quality on government take. The nature of this relationship -- whether this represents the result of a "corruption premium" paid by US MNCs or the exploitation of poor governance in negotiating government take -- is not completely clear. The evidence presented does, however, indicate that potential forms of bargaining power other than institutional quality (e.g., outside options to the deal) do increase government take, indicating that bargaining power may nonetheless be an important factor.

Africa's Growth Trap: A Political-Economy Model of Taxation, R&D and Investment

Why do so many African governments consistently impose high tax rates and make little investment in productive public goods, when alternative policies could yield greater tax revenues and higher national income? We posit and test an intertemporal political economy model in which the government sets tax and R&D levels while investors respond with production. Equilibrium policy and growth rates depend on initial cost structure. We find that in many (but not all) African countries, low tax/high investment regimes would be time-inconsistent. For pro-growth policies to become sustainable, commitment mechanisms or new production techniques would be needed.time consistency, agricultural policy, economic growth

Outsourcing Jobs? Multinationals and US Employment

Critics of globalization claim that US manufacturing firms are being driven to shift employment abroad by the prospects of cheaper labor. Others argue that the availability of low-wage labor has allowed US based firms to survive and even prosper. Yet evidence for either hypothesis, beyond anecdotes, is slim. Using firm-level data collected by the US Bureau of Economic Analysis (BEA), we estimate the impact on US manufacturing employment of changes in foreign affiliate wages, controlling for changing demand conditions and technological change. We find that the evidence supports both perspectives on globalization. For firms most likely to perform the same tasks in foreign affiliates and at home ("horizontal" foreign investment), foreign and domestic employees appear to be substitutes. For these firms, lower wages in affiliate locations are associated with lower employment in the US. However, for firms which do significantly different tasks at home and abroad ("vertical" foreign investment), foreign and domestic employment are complements. For vertical foreign investment, lower wages abroad are associated with higher US manufacturing employment. These offsetting effects may be combined to show that offshoring is associated with a quantitatively small decline in manufacturing employment. Other factors, such as declining prices for consumer goods, import competition, and falling prices for investment goods (which substitute for labor) play a more important role.

Does Direct Foreign Investment Affect Domestic Firms' Credit Constraints?

Firms in developing countries cite credit constraints as one of their primary obstacles to investment. Direct foreign investment, by bringing in scarce capital, may ease domestic firms' credit constraints. Alternatively, if foreign firms borrow heavily from domestic banks, they may exacerbate domestic firms' credit constraints by crowding them out of domestic capital markets. One plausible mechanism by which this may happen is indirect. Foreign firms may be more experienced and have better financial ratios and thus, be a safer bet for lending institutions. Using firm-level data from the Ivory Coast for the period 1974-1987 we test the following hypotheses: (1) domestic firms are more credit constrained than foreign firms and (2) borrowing by foreign firms exacerbates the credit constraints of domestic firms. Results suggest that domestic firms are significantly more credit constrained that foreign firms and that borrowing by foreign firms aggravates domestic firms' credit constraints. By splitting the sample into state-owned (SOE) and privately owned domestic enterprises we are able to show that SOEs are less financially constrained than other domestic enterprises, consistent with the notion of a 'soft budget constraint'. Borrowing by foreign firms affects only privately owned enterprises. Finally, we explore possible explanations for the crowding out effect.

AN AFRICAN GROWTH TRAP: PRODUCTION TECHNOLOGY AND THE TIME-CONSISTENCY OF AGRICULTURAL TAXATION, R&D AND INVESTMENT

Why do so many African governments consistently impose high tax rates and make little investment in productive public goods, when alternative policies could yield greater tax revenues and higher national income? We posit and test an intertemporal political economy model in which the government sets tax and R&D levels while investors respond with production. Equilibrium policy and growth rates depend on initial cost structure. We find that in many (but not all) African countries, low tax/high investment regimes would be time-inconsistent, primarily because production technology requires relatively large sunk costs. For pro-growth policies to become sustainable, commitment mechanisms or new production techniques would be needed.International Development, Research and Development/Tech Change/Emerging Technologies,
