We suggest that the geographical patterns of income differences across the world have deep underpinnings. We emphasize that economic development is a complex process driven by economic, political, social, and biophysical forces. Some economists have argued that the patterns reflect mainly the...

Are smarter machines our children's friends? Or can they bring about a transfer from our relatively unskilled children to ourselves that leaves our children and, indeed, all our descendants - worse off? This, indeed, is the dire message of the model presented here in which smart machines...

Do robots raise or lower economic well-being? On the one hand, they raise output and bring more goods and services into reach. On the other hand, they eliminate jobs, shift investments away from machines that complement labor, lower wages, and immiserize workers who cannot compete. The net...

This paper presents the theoretical underpinnings of the MSG2 simulation model of the world economy. The MSG2 model is a dynamic general equilibrium model of the world economy which pays particular attention to the relation between stocks and flows and intertemporal constraints. The formation of...

The search for "growth-oriented adjustment programs" reflects a widespread malaise concerning IMF stabilization programs in countries suffering from external debt crises. A new orthodoxy is emerging from this search, which links recovery in the debtor countries to a shift to "outward-oriented"...

This paper uses a global macroeconomic simulation model to identify the factors that have contributed to global trade and financial imbalances in the 1980s. After investigating the properties of monetary and fiscal policies in the model, we examine whether the budgetary shifts in the OECD...

This paper offers a theoretical framework for studying the inter-actions of energy prices and economic growth. The incorporation of energy prices and quantities in a macroeconomic setting focuses on (1)the aggregate technology; (2) the interdependence of energy producers and consumers in the...

Many of the crucial debates in development economics are encapsulated in the question of economic convergence. Is there a tendency for the poorer countries to grow more rapidly than the richer countries, and thereby to converge in living standards? Some recent research on endogenous growth has...

The volatility of the world economy since the breakdown of the Bretton Woods par value system of exchange rates has led many policymakers and economists to call for reform of the international monetary system. Many critics of the current "non-system" call for tighter international rules of the...

In a series of papers, my colleagues and I have demonstrated that levels of per capita income, economic growth, and other economic and demographic dimensions are strongly correlated with geographical and ecological variables such as climate zone, disease ecology, and distance from the coast....
