Fortress Europe: Jericho or Château d’If?

Traditional analysis of customs union formation suggests that it leads to an increase in members' external tariffs. This paper stresses two aspects of European trade and trade policy—a large volume of intra-industry trade between similar countries and a political motivation for tariffs—and highlights a role for tariff coordination in a model of differentiated products in which tariffs affect domestic costs and thus export prices and the magnitude of monopolistic rents. We show that when workers choose the tariffs and receive but a small portion of tariff revenues, the union's tariff wall falls.     

Ranking of information systems in agency models: an integral condition

Summary. We provide a condition for ranking of information systems in agency problems. The condition has a straightforward economic interpretation in terms of the sensitivity of a cumulative distribution with respect to the agent's effort. The criterion is shown to be equivalent to the mean preserving spread condition on the likelihood ratio distributions. Received: November 10, 1999; revised version: February 17, 2000     

Epidemiology of unintentional drowning in a metropolis of the French Mediterranean coast: a retrospective analysis (2000–2011)

Drowning affects more than 500,000 people worldwide and is responsible for at least 350,000 deaths each year. In France, 1235 drowning resulting in 496 deaths were recorded in the summer 2012. This retrospective study has investigated the epidemiology of drowning in the city of Marseille (South of France) between 2000 and 2011. We identified 449 cases of unintentional drowning. The highest incidence was found among males with a median age of 36 years. The incidence was 5.3 victims per 10,000 inhabitants with a mortality rate of 1.2 per 10,000. These accidents occurred mainly at sea (89%) and during the summer season. A majority of drowning victims (69%) were admitted in a hospital. This is the only study in France to analyse data on drowning throughout the year and over a long period. Drowning is a serious condition burdened by 22% of victims who die.     

Agriculture and climate change in global scenarios: why don't the models agree

Agriculture is unique among economic sectors in the nature of impacts from climate change. The production activity that transforms inputs into agricultural outputs involves direct use of weather inputs (temperature, solar radiation available to the plant, and precipitation). Previous studies of the impacts of climate change on agriculture have reported substantial differences in outcomes such as prices, production, and trade arising from differences in model inputs and model specification. This article presents climate change results and underlying determinants from a model comparison exercise with 10 of the leading global economic models that include significant representation of agriculture. By harmonizing key drivers that include climate change effects, differences in model outcomes were reduced. The particular choice of climate change drivers for this comparison activity results in large and negative productivity effects. All models respond with higher prices. Producer behavior differs by model with some emphasizing area response and others yield response. Demand response is least important. The differences reflect both differences in model specification and perspectives on the future. The results from this study highlight the need to more fully compare the deep model parameters, to generate a call for a combination of econometric and validation studies to narrow the degree of uncertainty and variability in these parameters and to move to Monte Carlo type simulations to better map the contours of economic uncertainty.     

Does marketing and sales integration always pay off? Evidence from a social capital perspective

Building on social capital theory, we view the marketing and sales interface as a set of inter-group ties and investigate how cross-functional relationships may facilitate the development of social capital associated with value creation. Our findings suggest that social capital embedded in marketing and sales relationships can inhibit a firm’s performance depending on the characteristics of its customers. Our results also demonstrate that managing the marketing and sales interface at different levels of customer concentration is critical to the success of a firm’s performance.     

The causes of unemployment in France: a flow approach

A flow model is used to identify the causes for rising unemployment in France between 1978 and 1990. Two flow equations are estimated as functions of exogenous factors such as aggregate demand, factor costs, structural shifts and long-term factors and then used in simulations for the level of unemployment. It is shown that the main reason for high unemployment in France is a slow down in the demand for labour due to high labour and energy costs in the early 1980s and to tight aggregate demand over the whole period.Change in the labour supply have had an increasing impact in recent years.     

The periurban city: why to live between the suburbs and the countryside

The last 30 years have witnessed the emergence of a new pattern of urban development in France, called the periurban belt. It is defined as a belt outside the city occupied both by households and farmers. We develop a residential model in which households commuting to an employment center may choose to live with farmers in this mixed belt because they value the rural amenities created by farming activities. Both types of agents compete on the land market and the equilibrium conditions allow us to obtain an analytical solution and to provide some insights about the robustness of the periurban form against decreases in commuting costs. Finally, the model is calibrated on French data.     

Breaking up the collective farms

The de‐collectivization of Vietnamese agriculture was a crucial step in the country's transition to a market economy. The assignment of land‐use rights had to be decentralized and local cadres ostensibly had the power to capture this process. We assess the realized land allocation against explicit counter‐factuals. Depending on the region, we find that 95–99 percent of maximum aggregate consumption was realized by a land allocation that generated lower inequality overall, with the poorest absolutely better off. We attribute this outcome to initial conditions at the time of reform and actions by the centre to curtail the power of local elites.
