Understanding how producers make decisions to allot acreage among crops and how decisions about land use are affected by changes in prices and their volatility is fundamental for predicting the supply of staple crops and, hence, assessing the global food supply situation. The innovations of the present paper are estimates of monthly (i.e. seasonal) versus annual global acreage response models f...

This paper studies how software agents influence the market behavior of human traders. Programmed traders with a passive arbitrage seeking strategy are introduced in a double auction market experiment with human subjects in the laboratory. As a treatment variable, the influence of information on the existence of software agents is investigated. We found that common knowledge about the presence ...

The paper considers a regression approach to pricing European options in an incomplete market. The algorithm replicates an option by a portfolio consisting of the underlying security and a risk-free bond. We apply linear regression framework and quadratic programming with linear constraints (input = sample paths of underlying security; output = table of option prices as a function of time and p...

There is an ongoing debate about the credit card industry regarding how effective competition has been at reducing prices. Some experts argue that intense competition is clearly evident and leads to low prices that contain no excess profit. However, other experts find evidence both in price data and in market concentration that competition has failed. A model is presented here showing that if t...

Today topic is market equilibrium. The basic elements of a market are buyers and product (and there are also potentially sellers). The goal is to nd prices that clear the market. Namely, under those prices every product is completely sold, and there is no remaining demand. In other words, we would like to achieve a state where demand equals supply. This is probably one of the most important con...

Economic models of land allocation may lead to expectations for farmer response that “surprisingly" do not materialize, if market prices fail to reflect the value of farmers' product. “Shadow prices" rather than market prices explain resource allocation better for farmers who attach significant non-market values to their own crops. I extend the theoretical model in Arslan and Taylor (2008) to e...

We investigate under which conditions price competition in a market with matching frictions leads to sorting of buyers and sellers. When buyer’s search strategies are directed by the market prices offered by sellers, positive assortative matching obtains only if there is a high enough degree of complementarity between buyer and seller types. The relevant condition is root-supermodularity ; i.e....

The goal of this paper is to test whether changes in the marketing margin between the farm and the retail prices can result in an asymmetric relationship between the farm and the retail prices in the rice market of Taiwan. By separating the transaction cost variation into two regimes, this paper utilizes a two-regime TVECM with the error correction term serving as the threshold variable to crea...

Even though economic models have been relatively successful in explaining the long run patterns of house prices, they have more difficulties in explaining short run developments of the housing markets. However, the fact that during such ‘bubbles’ the spatial pattern of house prices, which can mainly be attributed to accessibility differences, usually remains unchanged, suggests that the irratio...
