The Trade Effects of Indian Antidumping Actions

Antidumping (AD) has emerged as the most widespread policy impediment to trade in the last 25 years. One of the surprise proliferators of AD in the lesser developed world has been India, which has filed an outstanding number of 285 cases between 1992 and 2002. In this paper, I study empirically the effect of Indian AD cases on trade flows from other countries. I also look at the effect of AD cases on trade diversion from countries subject to or “named” in AD investigations to non‐subject or “non‐named” countries and conclude that Indian AD policy is effective. I use a unique dataset combining AD data from the World Trade Organization with trade data from Comtrade. The empirical model is estimated via the Arellano–Bond procedure.     

Informational efficiency with ambiguous information

This paper proves the existence of fully revealing rational expectations equilibria for almost all sets of beliefs when investors are ambiguity averse and have preferences that are characterized by Choquet expected utility with a convex capacity. The result implies that strong-form efficient equilibrium prices exist even when many investors in the market make use of information in a way that is substantially different from traditional models of financial markets.     

On the Feasibility of Interest Rate Control: The Role of Disequilibrium and Adaptive Learning

A model is constructed which derives an inverse relationship between real rate of interest and inflation rate following a disproportionate change in money supply. It is argued that such an inverse relationship paves the way for successful control of the nominal interest rate. It is analytically demonstrated that the state space is divided by a separatrix containing a stable zone and an unstable zone. If the initial inflation and the dynamics of inflationary expectations lie in the stable zone, then the monetary authority can peg the nominal interest rate without risking runaway inflation or deflation. The unstable zone, however, keeps the possibility of the cumulative process alive.     

Immigrant selection before and after communism

The end of the Soviet Union and communist regimes throughout Eastern Europe led to sudden increases in emigration and large changes in wage inequality. This has provided a unique opportunity to understand how these changes altered incentives to emigrate during the transition period. In this paper, I analyze immigrant selection before and after the fall of the Soviet Union within a Roy Model framework, in which the relative return to skills determines the skill composition of immigrants. Using micro-level data from Russia, Ukraine and Bulgaria, matched to Census data on immigrants from these countries in the United States, Spain and Greece in the post-Soviet period, I find evidence of positive selection of immigrants in the US, and negative selection for Greece and Spain. Using retrospective data from Ukraine during the communist period, I find that selection among Soviet men in the US was intermediate and selection among women was positive.     

Healthcare resource utilization and costs by age and joint location among osteoarthritis patients in a privately insured population

Aims: To compare healthcare resource utilization and costs between patients aged 18–64 years with osteoarthritis (OA) and matched controls without OA in a privately insured population.

Methods: Patients with OA were selected from de-identified US-based employer claims (Q1:1999–Q3:2011). The index date was defined as the first OA diagnosis indicated by ICD-9-CM codes. One year before and after the index date were defined as the baseline and study periods, respectively. A second OA diagnosis during the study period was also required. Patients with OA were matched one-to-one on age, gender, index date, and minimum length of follow-up to controls without OA. Baseline characteristics and study period resource utilization and costs (2016 USD) were compared between cohorts.

Results: This study identified 199,539 patients with OA (knee: 87,271, hip: 19,953, hand: 15,670, spine: 12,496). The average age was 54 years, and 58% were female. OA patients had higher healthcare resource utilization than matched controls in inpatient, emergency room, and outpatient settings (p?p?Limitations: This sample, obtained using claims data, only includes patients who were actively seeking care for OA and were likely symptomatic. Asymptomatic patients would likely not be captured in this analysis.

Conclusions: Patients with OA incur greater healthcare resource utilization and costs than patients without OA, with substantial variation by joint location.     

Green productivity and bilateral trade flows in an augmented gravity model – A panel data analysis

Motivated by the debate in the trade liberalization and the environment literature, this article examines the effect of enhancing green productivity (GP) on bilateral trade flows. The uptake of per capita ISO14001 certification counts is used to measure GP. The existing literature provides other key determinants of bilateral trade flows. This article employs an augmented gravity model and presents panel data analysis on 26 countries from 1995–2004. Since GP is closely related to quality management, this article also examines the joint effect of the measure of quality management systems (QMS) and the measure of GP. Several fixed effects regression equations are estimated. The results support the hypothesis that enhancing green productivity is a positive and statistically significant determinant of real bilateral exports. The joint significance of the measures of GP and QMS is also supported. This article lends empirical support for the new trade theory and Linder's hypothesis and is consistent with those obtained in the existing literature.
