U.S. live cattle markets have experienced dramatic shifts in marketing methods over the past two decades, changing the way live cattle prices are discovered. We identify relationships between prices of the five major live cattle marketing regions using Granger causality and directed graph analysis. The two approaches complement each other and reveal that interweek and intraweek price discovery roles for given markets differ. Evidence indicates that Colorado, though a minor market in terms of relative volume, has become an important source of interweek price information to other markets.

China has become the largest importer of roundwood and lumber products in recent years. In this study, the degree of competition among major supplying countries in China's import market is measured through the inverse residual demand elasticity over 1995–2015. Time-series properties of the data are considered through the autoregressive distributed lag model. The analysis reveals that market power exists in roundwood and lumber markets for a few supplying countries. The suppliers in the lumber import market have more market power than those in the roundwood market. Individual countries with substantial market power have more fluctuations in trading volumes.

We estimate an error correction model representing demand for leafy green vegetables but generalize the structure to allow for adjustment to one conspicuous shock. We investigate whether the adjustment rate to the U.S. Food and Drug Administration's (FDA) 2006 warning that fresh spinach was contaminated with deadly bacteria was distinct from the overall adjustment rate. Our model allows consumers to correct both for past errors and for any errors in their reaction to the shock. This method yields an estimate of the adjustment rate to the policy shock and points to an improved estimate of the duration of policy impacts.

This paper examines the price discovery function for three U.S. wheat futures markets: the Chicago Board of Trade, Kansas City Board of Trade, and Minneapolis Grain Exchange. The maintained hypothesis is that futures markets search more for information than cash markets to find an equilibrium price, thus greatly improving the price discovery function. The tests reveal the existence of one equilibrium price across the three futures markets in the long run, but no cointegration among prices in the three representative cash markets.

LL601 is a genetically modified rice variety and unapproved for commercial use. Its presence was found in commercial shipments of U.S. rice in 2006. This article explores its impact on prices and volume marketed for both the United States and Thailand, the major export competitor. The results show a significantly adverse but short duration effect on the U.S. rice market and little to no effect on the Thai rice market.

Unlike recent contributions in the field, which discuss the geography of British overseas investments, this article focuses on the growth of capital exports from Great Britain during the period 1870–1913. Using a broader concept of foreign investments, which includes foreign direct investments (FDIs), and refocusing on the push and pull factors emphasised in earlier literature, we propose a framework able to capture the long-run determinants of British capital exports. Moreover, the framework includes elements suggested by early and recent works such as the institutional setup of the international economy and the evolution of world trade. The most relevant result, in an error correction model environment, is that the timing of British overseas investments in the long run seems to be related to the evolution of world trade, domestic growth and to the role of India as a colony. On the other hand, the attraction elements of the borrowing countries, captured by the risk-adjusted realised rates of return abroad, have been proven to matter in the short run.

Although it is commonly believed that democracy promotes public services such as education, efforts have just started to evaluate empirically how the recent trend of democratization affects education services in the developing world. This article reports on the first regionwide investigation in East Asia. By studying the effects of democracy on multiple education indicators in a time-series-cross-section dataset of eight East Asian countries/political entities, the article examines whether democratic governments increase education spending and access and which social groups are favored in the process. The statistical results, which are corroborated by findings from two case studies, show that democracy plays a progressive role in promoting education spending and school enrollment at the basic level in East Asia.

A survey of nonlinear multivariate macro empirical models is attempted. Although theory may suggest that nonlinearity is to be expected, empirical studies have difficulty in discovering strong consistent effects. Regime switching techniques appear to be the most successful and evidence of nonlinearity is most found for interest rates. Most of the studies emphasize model fitting rather than model evaluation, which limits their usefulness.
