The consumption based asset pricing model: A note on potential tests and applications

Breeden's demonstration that Merton's multi-beta capital asset pricing model can be collapsed into a single-beta model where betas are computed with respect to aggregate consumption is an important theoretical advance. Nonetheless, Breeden's model retains many of the empirical problems that beset Merton's earlier version. In general the consumption betas will be nonstationary, so that the state variables must be observable for the model to be estimated.     

Office triage and the physician's supply curve

This paper contains a theoretical and empirical model of the physician firm. The utility maximizing physician chooses the number of hours of labor to supply and the mix between patient visits and time per visit. Theory suggests that a serious specification error may occur if one estimates the labor supply curve and patient demand curve without simultaneously estimating the mix between patient visits and time per visit. A Chi-Square specification test reveals that this “triage” model statistically dominates the simple supply/demand model. Estimation results indicate relevant backward-bending labor and negatively sloped service supply functions.     

Has the United States Overinvested in Housing?

Several economists have concluded that housing investment has been excessive relative to industrial investment in the U.S. Most blame provisions of the federal income tax that favor owner-occupied housing.
This paper poses the question within a two-sector neoclassical growth model which permits the social return to housing to differ from that to non-housing. The model is estimated using national income accounts and capital stock data from 1929 to 1983. The conclusion is that the return to housing capital is about half that to non-housing capital and that the housing stock should be about 75% of its 1983 volume.     

Money substitutes and monetary policy in the U.K., 1922–1974

In the U.K., following the publication of the Radcliffe Report, it was widely believed that monetary policy was impotent because any attempt to make use of monetary policy would be fully offset by perfect money substitutes which were not controlled by the monetary authorities. This paper tests whether such substitutes exist. The technique is to fit a money demand function to a long run of data allowing the interest elasticity to vary from observation to observation, and using a procedure which permits infinite values of the elasticity. It was found that, although the elasticity does vary, no observation was consistent with the Radcliffe view. This was true for both interest rates tried, and the function proved very stable when tested. We conclude that the Radcliffe Hypothesis can be decisively rejected.     

Every story tells a picture: Lessons from cartoons on corporate governance

While pictures tell stories, in the case of cartoons, stories also tell pictures. A theory of cartooning suggests that cartoons reflect public sentiment toward issues. As such, cartoons are a useful way of gauging and tracking public sentiment over time. This article uses a historical cartoon analysis to track public sentiment toward issues surrounding corporate governance. Specifically, it compares what cartoons reflected prior to the economic crash of 2008 and what they portrayed after. The criteria of narrative, location, binary struggle, and normative transfer were used as a framework to analyze 258 cartoons. We found that three major changes emerged after the 2008 crash that hold important lessons for those who govern corporations: the public's concern is no longer so much about corporate and individual fraudulent behavior as it is about corporate and individual greed; there is an impression that corporations do not do bad things so much as they do not do any good things; and ordinary people, workers, and taxpayers are those who suffer most when corporations are not governed well.     

Specialization,diversification, and productivity: a panel data analysis of rice farms in Korea

This article examines the microeconomics of productivity associated with specialization/diversification in production activities, with an application to Korean rice farms. Korean rice farms tend to be very small and highly specialized. Our analysis examines the productivity effects associated with both farm size and farm specialization/diversification in Korean agriculture. Relying on farm‐level panel data, the analysis studies farm productivity in a multi‐input multi‐output context, accounting not only for changes in inputs and technical change in rice production, but also for the role of diversification in the production of other crops in current and previous periods. We find positive but small productivity gains from farm diversification. These gains come mostly from complementarity effects across farm outputs, with minimal effect of scale economies. The positive complementarity effects work against nonconvexity effects, which provide strong productivity incentives for rice farms to specialize.     

Scanning for discounts: examining the redemption of competing mobile coupons

Coupons research has typically focused on single-coupon redemption, with scant attention devoted to multiple, competing coupons. To bridge this gap, we observe supermarket shoppers who used their smartphones to scan products in-store, receiving both coupons for the scanned product and several others as a result. We model the determinants of redemption in this context, particularly net price range (NPR), coupon value, brand loyalty, and number of coupons. Latent class analysis uncovers two consumer segments: brand-focused shoppers (79.9%), who use internal reference prices, and deal-prone shoppers (20.1%), who use stimulus-based reference prices. Targeting by means of segment membership, NPR, and loyalty is indispensable: the same $0.50 coupon can have a redemption probability as low as 30% and as large as 80%, depending on these characteristics. Overall, the study sheds light on drivers of redemption under competition and provides managers with a blueprint to improve redemption rates by targeting shoppers with customized coupons.
