Market gardening has been increasing fast in Senegal. But farmers face high marketing risks: daily price fluctuations exceed an average 20% for some products, seasonality is strong, anticipation based on prices leads to cyclic movements. Farmers and market operators have found various forms of...

This paper shows the impact that investment in infrastructure may have on the efficiency of agricultural products markets. Using daily price series for the most important agricultural crop in Peru (potato), in 10 cities from 1995 to 2001, we show that there is enough evidence to conclude that...

External agents are frequently characterized as necessary for efficiency in team production settings. At the same time, these agents must be constrained from opportunistically exercising their enforcement capabilities. I argue that collective action costs and formal institutions (e.g., golden...

We examine the relationship between the optimal incentive contract and the firm’s decision to fire a manager for poor performance. We first derive some theoretical results using a simple principal-agent model, and then examine the empirical evidence on the incidence of forced turnover among...

Wine brokers are wholesale intermediaries. They belong to the category of the matchmaker intermediaries. These middlemen are not well known. Their role is to help buyers and sellers of bulk wine to meet and transact. Assuming that wine merchants appeal to brokers because they reduce transaction...

This paper presents a model of trust in which a principal chooses either to trust or monitor an agent who, in turn, chooses either to honor or exploit that trust. The principal's decision of whether to trust or monitor is based on the relative temptation an agent faces to exploit the principal's...

This paper examines the concepts of trust and trustworthiness in the context of a one-sided variation of the prisoner's dilemma, and it evaluates four different categories of solutions to the PD problem: changing player preferences, enforcing explicit contracts, establishing implicit contracts,...

Vector autoregressions are used to model price transmission through the coffee processing chain, from producers to the world market and from the world market to consumers. A comparison is made of price dynamics against a backdrop of two very different market structures: pre-1989, producers...

In this study, we empirically examine the extent of price rigidity using a unique store-level time series data set - consisting of (i) actual retail transaction prices, (ii) actual wholesale transaction prices which represent both the retailers' costs and the prices received by manufacturers,...

The paper assesses the usefulness of selective hedging strategies when combined with forecast techniques in the live hog contract. The use of routine futures and options hedging is not attractive relative to a cash-only strategy. However, forecasting and hedging can contribute to price risk...
