‘METALLIC NERVES’: SAN FRANCISCO AND ITS HINTERLAND DURING AND AFTER THE GOLD RUSH

As the gateway to the Californian goldfields, San Francisco experienced a demographic shock that had a lasting impact on its economy. Some writers see San Francisco's growth as having a parasitic influence on the city's hinterland through the anti-competitive behaviour of some corporations and the destruction of natural resources. I argue that San Francisco generated more productive external effects through the formation of human and social capital in the city itself, and by investment in further resource development elsewhere in California.     

Modelling the world economy at the 2050 horizon

Economic analysis is increasingly addressing long‐term issues (such as global warming) that require a dynamic baseline for the world economy. In this article, we develop a three‐factor (capital, energy, labour) macroeconometric (MaGE – Macroeconometrics of the Global Economy) model, and project growth for 147 countries to 2050. We improve on the literature by the following: (i) accounting for the energy constraint through dynamic modelling of energy productivity, (ii) modelling female participation rates consistent with education catch‐up, (iii) departing from the assumptions of either a closed economy or full capital mobility (by applying a Feldstein–Horioka type relationship between saving and investment rates), and (iv) offering a fully consistent treatment of the Balassa–Samuelson effect. These innovative features have a sizeable impact on projected GDP.     

Carcinoid of the intrahepatic ducts

Carcinoid tumors of the biliary tree are rare. To the best of our knowledge, this is the first reported case of an intrahepatic ductal carcinoid and the thirteenth reported case of biliary carcinoid. The radiographic appearance is variable. A brief review of the previously described cases is presented.     

A note on comparative statics and dynamics of stationary states

Certain results are communicated regarding effects of parameter changes, when the stationary state is stable, on the stationary state and an optimal paths in its neighbourhood in discrete time multi-sectoral optimal growth models where period utilities are discounted.     

African Americans in southern rural regions: The importance of legacy

This analysis reassesses the importance of the combined legacies of race, class, and culture by using the concentration of African Americans in a county as a general measure of this phenomenon for thirteen Southern states. Explanatory variables associated with labor force structure, social well-being and region provide evidence that those areas of the South with the highest concentrations of African Americans continue to be the most disadvantaged. These results suggest little change for metropolitan counties with increased concentrations of African Americans. The analyses point toward the need for a focused assessment of the efficacy of existing public and private programs to provide a foundation for overcoming the negative dimensions of the regional legacy.     

Severance Payment: Incentive or Lethargy Effect?

The aim of the paper is to determine the impact of severance payment on the motivation of the worker to make an effort, when there is a risk for him to be dismissed once his effort was made. We highlight through a two‐stage model the various factors which influence the dismissal decision by the firm and the worker's effort, such as the initial wage, the litigation costs and the relative bargaining powers of the parties when the relationship ends or goes on. In this context, we show that the impact of the severance payment paid ex post in case of dismissal on the level of effort chosen by the worker ex ante may depend on such characteristics.
