| Based on original trader surveys, this paper examines how agricultural traders operate in Benin and Malawi. Results indicate that the largest transaction costs are search and transport. The use of modern technology is limited. Search methods rely principally on personal visits by the trader, and quality control requires the presence of the trader at the time of purchase. This increases costs, as the trader has to travel a lot, and makes it difficult for trading enterprises to grow. Since enterprises remain very small, personal transport and search time represent a non-negligible share of marketing costs. |

| How can long-term unemployment be reduced by policy measures of the government? In this paper a growth-matching-model is developed, in which the unemployment pool consists of heterogeneous unemployed workers, short-term and long-term unemployed, and with an endogenous skill-depreciation of the long-term unemployed emerging as technical progress accelerates. For innovation countries characterized by rapid technical progress we show that through subsidizing vacancy creation which causes a substitution and an income effect long-term unemployment can be reduced. Since the positive substitution effect implied by subsidizing vacancy creation outweighs the negative income effect induced by taxing the household's income, a positive employment effect results... |

| How does technical progress affect long-term unemployment? The relationship between long-term unemployment and the rate of growth attributable to technical progress is evaluated in a growth-matching-model with heterogeneous jobless workers and with endogenously determined long-term unemployed resulting from skill-depreciation. For innovation economies characterized by high steady-state levels of capital intensities the model shows that, due to a capitalization effect and a qualification-mismatch effect, increasing technological progress has adverse implications for long-term unemployment. Furthermore, for imitation economies with low steady-state capital intensities increasing technological progress can be either favorable or less favorable for long-term... |

| We develop a model of search in which a researcher chooses the size of sequential batches of samples to test. While earlier work has considered similar questions, the contribution of this paper is to use the search model to place a value on the marginal research opportunity. The valuation of such opportunities may be of little interest or relevance in many of the contexts in which search models are employed, but we apply our analysis to an area of considerable societal interest: the valuation of biological diversity for use in new product research. While data from which to make inferences are limited, we find that, using plausible estimates of relevant parameters, the value of biodiversity in these applications is negligible. |

| The effects of "localized depletion" of a pelagic fishery (herring) on a non-extractive marine activity (tourism) are investigated. Proponents of the localized depletion theory claim that intense fishing effort can lead to areas that are unsuitable for predators like tuna, groundfish, and whales. This leads to poor outcomes for the fishing and whale-watching industries. However, there has been no consensus in the scientific community about the existence of this phenomenon. Localized depletion would be consistent with an economic theory of joint production, in which nearshore herring stocks are an input in production of both herring and whale-watching trips. A unique dataset of daily whale-watching outcomes is combined with fishing effort and oceanographic... |
