This paper investigates the optimal retirement of an individual in the presence of involuntary unemployment risks and borrowing constraints in a complete market with frictions. We use an intensity model and loading factors to illustrate the involuntary unemployment risks and frictions in...

<section xml:id="fut21648-sec-0001"> Psychological barriers are prevalent among various asset classes, and it is important to consider their impact on the prices of derivative securities. This paper demonstrates the potential existence of such barriers on the S&P 500 Index and examines their impact on this index's rate of return...</section>

This research forecasts peak call volume to allow a centralized call center to minimize staffing costs. A Gaussian copula is used to capture the dependence among nonnormal distributions. Peak call volume can be easily and more accurately predicted using the marginal probability distribution with...

The effect of aggregation on estimates of stochastic frontier functions is considered. Inefficiency is assumed associated with the individual units being aggregated. In this case, the aggregated data have a closed skew normal distribution. Estimating the parameters of a closed skew normal...

The Journal of Cooperatives (formally titled the Journal of Agricultural Cooperation) was published as a print journal from 1986 to 2003. The journal resumed publication as an electronic journal in 2007. This article provides a short history of the journal, analyzes trends in authorship,...

Drought impact both producers and agribusinesses. This study investigates the impacts of the 2004-2007 droughts on Oklahoma grain handling and fertilizer supply firms. The results indicated an average decline in firm revenues of 30%. Individual firms had single year revenue declines of 85% and...

The speed of shipping cotton from warehouses has become an important issue for the cotton industry. This paper examines issues relating to costs and benefits of an increased cotton shipping standard. The value chain model is used to identify improvements in incentives, information flow and...

Fertilizer price volatility has increased dramatically. This research examines cash purchase and warehouse strategies. Seventeen years of Oklahoma fertilizer prices are examined. The results indicate that mechanical cash purchase strategies can be used to reduce the average cost or variance for...

The expert contributors – both Asian and Western – illustrate that as G20 members, many Asian countries are now able to showcase their increasing powers and influence on global issues. Within this context, and via multidisciplinary economic and political science perspectives, the...

The objective of this article is to address heteroscedasticity in the stochastic frontier cost function using aggregated data and verify it using a Monte Carlo study. We find that when the translog form of a stochastic frontier cost function with aggregated data is estimated, all explanatory...
