The price relationship between organic and non-organic vegetables in the U.S.: evidence from Nielsen scanner data

This study investigates price relationships between organic and conventional carrots, tomatoes, and lettuce in the U.S. utilizing Nielsen scanner data from 2006–2015. We employ a threshold vector error correction model (TVECM), threshold vector autoregressive model (TVAR), and threshold cointegration test to test whether market integration exists between organic and conventional vegetables as well as the existence of asymmetric price transmission. The results find positive long-run relationships between organic and conventional prices of carrots and tomatoes and show the existence of asymmetric price transmission in price pairs of lettuce and tomatoes. Our findings suggest that the price relationship between organic and conventional vegetables varies by characteristics, such as shelf life, volatility in the price premium, and substitutability.     

Monetary Impacts and Overshooting of Agricultural Prices in an Open Economy

This article's focus is on the time adjustment paths of the exchange rate and prices in response to unanticipated monetary shocks. First, we expand the theoretical specification of the overshooting hypothesis by generalizing Dornbusch's model to include a third sector (i.e., agricultural prices). Second, we employ Johansen's cointegration test along with a vector error correction model to investigate whether agricultural prices overshoot in an open economy. The empirical results indicate that agricultural prices adjust faster than industrial prices to innovations in the money supply, affecting relative prices in the short run, but strict long-run money neutrality does not hold.     

The Reform of Medical Malpractice Law:

The major stimulus for the extensive, state level, reform of medical malpractice during the past two decades was the widespread belief in a malpractice crisis. The perception of a crisis arose in the 1960s largely because of what was viewed as sudden and dramatic increases in the malpractice liability of physicians. However, historical data demonstrate that the common perception that physician liability increased suddenly and dramatically beginning in the 1960s Is incorrect. Since malpractice reform has been based upon the false premise that the medical malpractice liability system, previously working smoothly, was in disarray, the soundness of much of the malpractice reform which has occurred in the past two decades is questioned.     

Decentralized international exchange

Abstract.  We utilize a random‐matching model to examine the relationships between market frictions and international trade. In our setting, an individual may choose to search abroad where she may have a cost advantage, but is less likely to meet potential trading partners, owing to higher market frictions. Interestingly, we find that international trade may be associated with lower welfare than autarky. We show how this is due to price distortions resulting from bargaining when there are opportunities for exchange across countries. JEL classification F10, C78, D83     

Product quality and competition: evidence from the broadband industry

Access to high-quality broadband internet is important in many different respects such as in communication, education, commerce and information acquisition. We investigate the relationship between the number of broadband providers in an area and the quality of broadband service provided where download speed is used as a proxy for quality. We find that increased competition in an area positively affects the access to fast download speeds. This finding is robust to three different top download speeds tested. Additionally, a theoretical model is provided which shows that competition can decrease the profits associated with offering slow speeds; this gives an incentive for providers to offer higher speeds as a way to increase profits.     

Allocating audit resources to detect fraud

This paper addresses how to allocate audit resources across different auditable units when misstatements may occur in any or all of the units. We consider two benchmark scenarios. In the first, the extent of overstatement affects only the cost of detection, but not the effectiveness of audit inputs in determining the likelihood of detection. In the second, overstatement directly affects the likelihood of detection but not audit cost. In a two location setting, if overstatement affects only audit effectiveness, the realized value at one location has no impact on the reported value at the other. In addition, the auditor allocates an identical amount of audit resources to each location. In contrast, if overstatement affects only audit cost, the agent’s reporting strategy reflects interdependencies between both realized values and audit costs across locations.
