Barter Trading as a Microeconomics Teaching Device

Karpoff reports on a “barter trading game” in which students exchanged real goods over a period of seven weeks with different market constraints imposed each week. Student comments about the exercise were favorable.     

Border Bargains and the “New” Sovereignty: Canada-US Border Policies from 2001 to 2005 in Perspective

From 2001 to 2005 Canada and the US dramatically altered the way each country views its border. In response to the attacks on New York City and Washington DC, Canada and the US entered into three important partnerships: the Smart Borders Agreement (SBA), the Container Security Initiative (CSI), and the Security Prosperity Partnership (SPP). These arrangements will be conceptualised here as “tacit bargains” whereby Canada provided the US with security in hope of renewed trust and economic accessibility. These “tacit bargains” required a concession of traditional state sovereignty so that stable and predictable relations between both countries could continue. While this process is ostensibly a violation of state sovereignty, the argument presented here is that these three “tacit bargains” represent a transition of “old” sovereignty to “new” sovereignty.     

A pre-diffusion growth model of intentions and purchase

In this paper, we investigate whether information on the history of purchase intentions is useful in predicting actual purchase behavior. The research is motivated by two factors. The first factor is the empirical finding in the literature that measuring intentions just prior to purchase provides better predictions of actual purchase as compared to when these intentions are measured earlier. The second factor is the role of the timing of the formation of intentions prior to purchase. While one stream of literature based on preference fluency predicts that early formation of intentions is more likely to lead to actual purchase, the other stream based on the memory-based “recency” effect predicts that formation of intentions just prior to purchase is more likely to lead to actual purchase. Together, these two factors motivate the potential need to account for the entire history of intentions prior to purchase. A canonical example of a market where intention histories are tracked is the movie industry, where “first choice” movie watching intentions are tracked up to (and in some cases beyond) the time of release. Accommodating the history of intentions in an econometric model that predicts actual box office performance is challenging due to the differing numbers of observations for the movies, the large numbers of observations for certain movies, as well as the role of various time-invariant and time-varying covariates influencing intentions. We propose a two-part model where the first part involves a hierarchical growth model that summarizes the trajectories of intentions via “growth factors.” These growth factors also reflect the role of the various covariates. The second part is a regression of the box office performance on the growth factors and other covariates. The models are simultaneously estimated within a Bayesian framework. Consistent with the previous literature, we find that including information on intentions improves our ability to predict behavior, with the recent intentions being the most informative. Importantly, when the history of intentions is accounted for, our results indicate that the data support the “recency” literature—intentions grow over time leading up to purchase, and this growth has a positive impact on opening box office performance. While a linear growth model performs best for most movies, there exists a subset of movies for which the quadratic growth model better captures the “spike” in intentions just prior to purchase. Further, accounting for information on the history of intentions dramatically improves model fit and forecasting performance relative to when only the intentions at one point in time (e.g., the ones just prior to purchase) are accounted for.     

The consequences to managers for financial misrepresentation

We track the fortunes of all 2,206 individuals identified as responsible parties for all 788 Securities and Exchange Commission (SEC) and Department of Justice (DOJ) enforcement actions for financial misrepresentation from January 1, 1978 through September 30, 2006. Fully 93% lose their jobs by the end of the regulatory enforcement period. Most are explicitly fired. The likelihood of ouster increases with the cost of the misconduct to shareholders and the quality of the firm's governance. Culpable managers also bear substantial financial losses through restrictions on their future employment, their shareholdings in the firm, and SEC fines. A sizeable minority (28%) face criminal charges and penalties, including jail sentences that average 4.3 years. These results indicate that the individual perpetrators of financial misconduct face significant disciplinary action.     

Surplus Value Production and Realization in Marxian Theory – Applications to the U.S., 1990–2015

ABSTRACT

Marx's Capital shows that surplus value can be produced in one industry, yet realized as profit (and possibly revenue) by other industries over the course of circulation. This paper highlights the separation between surplus value production and realization in Marx's work, and develops a new method for estimating surplus value production at the industry level to trace out transfers of surplus value across industries. The framework is based on the ‘New Interpretation’ and links money value added to surplus value production at the industry level. Data on value added by industry for the U.S. are used to estimate surplus value production by industry. The analysis allows comparison of surplus value production and realization in each industry. The pattern of differentials between surplus value creation and realization across industries sheds light on the processes of capitalist competition and points to a source of instability for capitalist economies.
