| We examine patterns of acquiring non-native languages in a model with two languages and two populations with heterogeneous learning skills, where every individual faces a binary choice of learning the foreign language or refraining from doing so. We show that both interior and corner linguistic equilibria can emerge in our framework, and that the fraction of learners of the foreign language is higher in the country with a higher gross cost adjusted communicative benefit. It turns out that this observation is consistent with the data on language proficiency in bilingual countries such as Belgium and Canada. We also point out that linguistic equilibria can exhibit insufficient learning which opens the door for government policies that are beneficial for both... |

| We present a real options model of an agent's decision to purchase or sell a good under conditions of uncertainty, irreversibility, and learning over time. Her WTP and WTA contain both the intrinsic value of the good and an option value associated with delaying the decision until more information is available. Consequently, the standard Hicksian equivalence between WTP/WTA and compen-sating and equivalent variation no longer holds. This helps to explain the WTP/WTA disparity often observed in laboratory experiments and surveys because subjects may have limited learning time and opportunities, thus generating option values. In contrast, the disparity may decrease or disappear entirely in real markets since agents are free to choose when to stop gathering... |

| Much of the job search literature assumes bilateral meetings between workers and firms. This ignores the frictions that arise when meetings are actually multilateral. I analyze the magnitude of these frictions by presenting an equilibrium job search model with an endogenous number of contacts. Workers contact firms by applying to vacancies, whereas firms contact applicants by interviewing them. Sending applications and interviewing applicants are costly activities but increase the probability to match. In equilibrium, contract dispersion arises and workers spread their applications over the different contract types. Estimation of the model on the Employment Opportunities Pilot Projects data set provides values for the cost of an application, the cost of an... |

| We present a first analysis of auction markets for specialty food products. We identify auction prices, trade volume and value for domestic and foreign origin specialty ham with geographical indications (GIs) which were actually sold in online auctions in Germany within a one-month period. Applying hedonic modeling, we examine potential factors that may influence online bidding behavior and final auction prices. We estimate positive auction price effects for weight, bidding activity, and auction length, that the domestic product is sold at a discount, that higher shipping cost have a negative impact on final prices, and that auctions ending on Fridays and Saturdays yield lower prices. The model may be used to estimate the value of GIs. In our example, we... |

| Consider a population of farmers who live around a lake. Each farmer engages in trade with his m adjacent neighbors, where m is termed the "span of interaction." Trade is governed by a prisoner’s dilemma "rule of engagement." A farmer’s payoff is the sum of the payoffs from the m prisoner’s dilemma games played with his m/2 neighbors to the left, and with his m/2 neighbors to the right. When a farmer dies, his son takes over. The son who adheres to his father’s span of interaction decides whether to cooperate or defect by considering the actions taken and the payoffs received by the most prosperous member of the group comprising his father and his father’s m trading partners. Under a conventional structure of payoffs, it is shown that a large span of... |

| We present a dynamic model of an agent's decision to purchase or sell a good under conditions of uncertainty, irreversibility, and learning over time. Her WTP contains both the intrinsic value of the good and a commitment cost associated with delaying the decision until more information is available. Consequently, the standard Hicksian equivalence between WTP/WTA and compensating and equivalent variation no longer holds. This finding has important practical implications as it implies that observed WTP values are not always appropriate for welfare analysis. |

| The provision for producers to update base acres and payment yields in the 2002 farm bill afforded an opportunity to test whether it was feasible to deliver a complex simulation model directly to producers. A Monte Carlo simulation model for assessing the economic impacts of the alternative base and yield options on individual farms was developed and made available to producers via the World Wide Web. The experiences and challenges from this collaborative extension and research effort are described, as well as the issues educators might consider before delivering complex software to a national audience via the Web. |

| There is in Europe a trend for privatisation and commercialisation of technical extension services for agriculture. At the same time, extension is supposed to support the contribution of multifunctional agriculture (MFA) to rural development. This article proposes an analytic framework to test whether performances of commercial extension enable to enhance the effectiveness of intangible investments in MFA context. Empirical investigations were realised about technical extension for cereal production in Ain (France) and Zeeland (Netherlands). It appears that [A] private extension providers hardly invest in R&D relevant to MFA context; [B] some farmers who contribute to MFA may lack technical knowledge when provided by commercial extension. |
