人工智能将为农机带来什么?

正相较古人,我们生活在这个充满技术进步的时代,可算得上是"特权一代"了。几乎所有事情都要靠自己手动完成的日子已经一去不复返,现在我们生活的世界上,很多工作都可以由机器、软件和各种自动流程接管。之所以有这样的改变,人工智能(AI)功不可没。人工智能是以"像人一样思考和行动"的出发点设计和编程的机器,虽然诞生的时日不长,尚处于萌芽阶段,但已经成为我们日常生活的重要组成部分,并且正在改变我们     

Stochastic Frontier Estimation of Market Power in the Food Industries

We use a modified version of the stochastic frontier model to estimate oligopoly markups above the perfectly competitive frontier, separating out deterministic markups from purely stochastic markups. Using data from 42 US food processing industries between 1990 and 2010, empirical results indicate a widespread incidence of oligopoly power, with Lerner indexes averaging approximately 21%. Further, the estimated markups increase with industrial concentration but decrease with price elasticities and imports. Finally, the estimated Lerner indexes are in the range of previous food industry estimates using New Empirical Industrial Organization (NEIO) models.     

The effect of consumer food creation on the food consumption experience

Two experiments show that the role the consumer plays in the creation of their food can affect the consumption experience. When guilt is present in the consumption of the food item, namely an unhealthy food item, having someone else create the food item increases taste evaluations, attitudes, and behavioral intentions. However, when guilt is not present, as in the case for healthy foods, there is no difference in food evaluations when the end consumer or another creates the food. These results have important implications for food retailers, food service establishment, and food delivery companies.     

Policy capturing in small‐group decision making: Using linear programming to assign factor weights for the NCAA Selection Committee's ranking decisions in the 2016 through 2018 men's basketball tournaments

We present a general approach for applying policy capturing to small‐group decision making and demonstrate the approach with the NCAA Selection Committee's rankings of the 68 teams in the three most recent Division I Men's Basketball Tournaments. We develop a linear programming model that minimizes the extent to which the evaluation of a lower‐ranked team exceeds that of a team ranked immediately above it. The result is a set of linear weights that approximates a group decision when the decision itself is demonstrably internally inconsistent in that a group ranks some teams higher than others despite a lower implied evaluation.

Good global citizen? ASEAN’s image building in the United Nations

ABSTRACT

Based on role theory, the article examines the images that ASEAN member governments project of their organization. It rests on a discourse analysis of 198 speeches in the United Nations General Assembly between 1998 and 2017. Findings suggest that ASEAN does not figure as a top priority for delegates and that an overarching ASEAN role conception is missing. However, their addresses reveal parameters on which a collective role conception can be built. Individual ASEAN countries undertake great efforts to project themselves as ‘good global citizens,’ a role conception that could also be applied to ASEAN.     

Inequality in turbulent times: income distribution in Germany and Britain, 1900–50

Using social tables, this article provides new data on inequality in Germany and Britain on an annual basis for the first half of the twentieth century. Inequality trends in these two countries tended to follow opposite patterns. The decline in inequality in Germany was interrupted during the First World War and the Nazi period, while in Britain the reversal took place between the end of the First World War and the Great Depression. Results show that the drop in inequality during the twentieth century in Europe did not follow secular trends, thus supporting the notion of inequality cycles.     

Financial knowledge among Iranian investors

This research is the first to describe financial knowledge in the Islamic Republic of Iran. Data were collected from a convenience sample of investors in the Tehran Stock Exchange. The data were used to examine objective and subjective knowledge as well as overconfidence in one's financial knowledge. The results indicated that compared with other populations, Iranians did not perform well on either basic or advanced financial knowledge questions, especially when the questions dealt with interest rates. This is likely related to the Islamic law ban on usury‐based investing. Regression analysis indicated that demographic charactristics related to basic financial knowledge were income, labour force status and being a student. Demographic characteristics related to advanced financial knowledge were education, labour force status and age. Higher income and education reduced the odds of being overconfident about one's financial knowledge, while being a student and male increased the odds. The article concludes with recommendations about future research as well as building a national financial education strategy.
