BILATERAL MARKET STRUCTURES AND REGULATORY POLICIES IN INTERNATIONAL TELEPHONE MARKETS

We develop models of bilateral oligopoly with traffic exchanges to study the competition and regulatory policies in the international telephone markets. Under the requirement of uniform settlement rates, the proportional return rule (PRR) inflates the rates and hence neutralizes PRR's effect on calling prices. Retail competition and PRR increase net settlement payments. Market efficiency is improved when there are multiple channels for traffic exchanges. Using a panel of 47 countries that exchanged traffic with the United States between 1992 and 2004, we test the effects of bilateral market structures and the U.S. policies. The empirical results support our theoretical findings.     

Fuel inventory and price relationships in the U.S. electric power sector under regulatory and market change

Long-run relationships among coal inventories at U.S. electric power plants, corporate bond rates and coal, natural gas, and electricity prices are estimated over the period July 1976 to October 2014. Tests for constancy of the long-run relationships show periods of instability which coincide with major regulatory events in the electric power sector. Deregulation of the natural gas and electricity markets are likely sources of instability for the period mid-1994 to mid-2001. Additionally, inventory behavior may have had a smoothing effect over instability caused by natural gas prices during the recent U.S. shale boom. Policy makers should be aware that altering the regulatory environment can result in considerable fluctuations in how firms’ inventory decisions interact with input and output markets and opportunity costs in the long run.     

SEQUESTERING CARBON ON AGRICULTURAL LAND: SOCIAL COST AND IMPACTS ON TIMBER MARKETS

Planting trees to sequester carbon has broad political appeal. However, effects of a major tree planting program on the agricultural sector and on timber markets are unclear. This paper examines social costs of sequestering carbon in tree plantations on U.S. agricultural land and investigates harvesting's effects on timber prices and on private timber producers' welfare. The analysis links a model of the U.S. agricultural sector that includes the land base in major production areas with a model of the U.S. softwood economy. Using current data on planting, maintenance, and harvesting costs for tree plantations and carbon sequestration rates, the models estimate the price and welfare effects of alternative carbon sequestration goals. Results indicate a range of outcomes. Consumers pay higher prices for food as farmers divert land from crops to trees. However, wood products consumers gain from falling timber prices if the trees enter commercial markets. Agricultural producers and landowners gain from higher commodity prices, but private forest owners lose. Large tree planting programs imply that policymakers must compensate private commercial tree planting to prevent farmers from displacing present tree plantations.     

Hazardous Waste Hits Hollywood: Superfund and Housing Prices in Los Angeles

This paper contributes to the ongoing debate concerning the effect of various actions taken by the U.S. Environmental Protection Agency under CERCLA, commonly known as the Superfund Program, on housing prices. This study uses a housing transaction panel dataset encompassing the five major counties of the Los Angeles Combined Statistical Area to estimate the program’s influence on the local housing market. Using house and time-varying census tract fixed effects, I am able to avoid many of the endogeneity problems seen in previous research attempting to measure the Superfund treatment effect. An estimate of the effect on housing prices is given for each of the major events that occur under a typical Superfund remediation. After controlling for confounding correlated unobservables, I find a 7.3 % increase in sales price for houses within 3 km of a site that moves through the complete Superfund program. The analysis gives evidence of positive price appreciation for housing markets and serves as a lower bound for measuring remediation benefits.     

Cross-subsidization and cost misallocation by regulated monopolists

While cross-subsidization is understood theoretically as involving the sustainability of a cost allocation scheme, it is invoked in regulatory policy contexts, such as the divestiture of AT&T, where costs of serving unregulated markets may be borne by ratepayers of regulated monopolies. We analyze two cross-subsidization tactics—cost misallocation and distorted technological choice — under a spectrum of regulatory cost allocation policies. These tactics lead to higher prices in regulated markets and inefficient production in unregulated markets. Welfare effects are discussed; we conclude with observations on strategic behavior and regulatory policy.     

ETHNIC DIVERSITY AND TRUST

Using data from U.S. states, I investigate the relationship between ethnic diversity and trust. I find a negative relationship between ethnic polarization and trust and a U‐shaped relationship between ethnic fractionalization and trust. According to my estimations, (a) going from an ethnic polarization index (PI) of 0 to an ethnic PI of 1 decreases trust by almost 12% points; and (b) trust is minimized when the ethnic fractionalization index is equal to 0.34.

Consumer‐benefiting exclusive territories

Abstract.  I investigate the effect of exclusive territories, which are typical vertical controls imposed by upstream firms. Using shipping spatial models, I consider an industry that consists of many independent local markets. An upstream monopolist restricts competition between downstream firms using exclusive territories. I find that exclusive territories reduce the prices of final products in all local markets in quantity‐setting competition. In price‐setting competition, they raise prices in half the local markets, reduce them in other markets, and also reduce the total consumer surplus. JEL classification: L42, R32     

THE ROLE OF HOUSE PRICES IN THE MONETARY TRANSMISSION MECHANISM ACROSS EUROPEAN COUNTRIES

This paper provides a discussion of the ‘housing market’ channels of the monetary transmission mechanism and offers some evidence of institutional differences in the European housing and mortgage markets. Using a number of Vector Autoregressive models, estimated individually for nine European countries over the pre‐EMU period, we find that house prices are significantly affected by interest rate shocks. The relative role of these interest‐rate‐induced fluctuations in house prices for private consumption is then investigated. We show that house prices may enhance the effects of interest rate shocks on consumer spending in those economies where housing and mortgage markets are relatively more developed and competitive.     

What are the effects of fiscal policy on asset markets?

We investigate the link between fiscal policy shocks and asset markets. Our results show that spending shocks have: a positive and persistent effect on GDP in the U.S. and in the U.K., while for Germany and Italy, such impact is temporary; a positive and persistent effect on housing prices; a negative effect on stock prices; and mixed effects on the price level. A VAR counter-factual exercise suggests that fiscal shocks play a minor role in the asset markets of the U.S. and Germany, and substantially increase the variability of housing and stock prices in the U.K., while government revenue shocks have increased volatility in Italy.     

PARTISAN POLITICS, INTEREST RATES AND THE STOCK MARKET: EVIDENCE FROM AMERICAN AND BRITISH RETURNS IN THE TWENTIETH CENTURY

We examine the relationship between government partisanship, interest rates and the mean and volatility of stock prices in the United States and United Kingdom. We suggest that traders in the stock market rationally expect higher (lower) post-electoral interest rates during the incumbency of the left-wing (right-wing) party – Democrats and Labor (Republican and Conservative) – and in election years when they expect the left-wing (right-wing) party to win elections. We hypothesize that expectations of higher (lower) interest rates decrease (increase) the mean and volatility of stock prices during the actual incumbency or even anticipation of a left-wing (right-wing) party holding the office of the chief executive. Results from empirical models estimated on data from U.S. and U.K. markets over most of the twentieth century statistically support our claims.     

Why firms set different export prices? Evidence from Spain

Using firm-level export data for the 2010–2014 period, we investigate the variation of export prices across and within Spanish manufacturing firms. We find that more productive firms set higher export prices. However, this result is not robust to controlling for other firm-level characteristics and alternative productivity measures. We show that firms set higher export prices in more distant markets and in destinations with high GDP per capita, and lower export prices in large and low-competition markets. These latter results suggest that firms adjust the quality of their products to destination characteristics.     

Cost-effectiveness of distributing naloxone to heroin users for lay overdose reversal in Russian cities

Abstract

Objective:

To evaluate the cost-effectiveness of distributing naloxone to illicit opioid users for lay overdose reversal in Russian cities.

Method:

This study adapted an integrated Markov and decision analytic model to Russian cities. The model took a lifetime, societal perspective, relied on published literature, and was calibrated to epidemiologic findings.

Results:

For each 20% of heroin users reached with naloxone distribution, the model predicted a 13.4% reduction in overdose deaths in the first 5 years and 7.6% over a lifetime; on probabilistic analysis, one death would be prevented for every 89 naloxone kits distributed (95% CI?=?32–260). Naloxone distribution was cost-effective in all deterministic and probabilistic sensitivity analyses and cost-saving if resulting in a reduction in overdose events. Naloxone distribution increased costs by US$13 (95% CI?=?US$3–US$32) and QALYs by 0.137 (95% CI?=?0.022–0.389) for an incremental cost of US$94 per QALY gained (95% CI?=?US$40–US$325). In a worst-case scenario where overdose was rarely witnessed and naloxone was rarely used, minimally effective, and expensive, the incremental cost was US$1987 per QALY gained. If national expenditures on drug-related HIV, tuberculosis, and criminal justice were applied to heroin users, the incremental cost was US$928 per QALY gained.

Conclusions:

Naloxone distribution to heroin users for lay overdose reversal is highly likely to reduce overdose deaths in target communities and is robustly cost-effective, even within the constraints of this conservative model.     

CREDIT,HOUSING COLLATERAL,AND CONSUMPTION: EVIDENCE FROM JAPAN,THE U.K., AND THE U.S.

The consumption behavior of U.K., U.S., and Japanese households is examined and compared using a modern Ando‐Modigliani style consumption function. The models incorporate income growth expectations, income uncertainty, housing collateral, and other credit effects. These models therefore capture important parts of the financial accelerator. The evidence is that credit availability for U.K. and U.S., but not Japanese, households has undergone large shifts since 1980. The average consumption‐to‐income ratio rose in the U.K. and U.S. as mortgage down‐payment constraints eased and as the collateral role of housing wealth was enhanced by financial innovations, such as home equity loans. The estimated housing collateral effect is similar in the U.S. and U.K. In Japan, land prices (which proxy house prices) continue to negatively impact consumer spending. There are negative real interest rate effects on consumption in the U.K. and U.S. and positive effects in Japan. Overall, this implies important differences in the transmission of monetary and credit shocks in Japan versus the U.S., U.K., and other credit‐liberalized economies.     

WIC PARTICIPATION AND MATERNAL BEHAVIOR: BREASTFEEDING AND WORK LEAVE

We examine the effects of the Women, Infants, and Children (WIC) Program on breastfeeding outcomes and maternal employment decisions. This research expands the existing literature using an alternative identification strategy and a broader set of outcomes. Using data from the Infant Feeding Practices Study II, we control for selection bias into WIC using the variation in food prices as an instrumental variable. The results of this study are robust to a number of specification and falsification tests. We find WIC decreases exclusive breastfeeding by nearly 50% and increases work leave duration by over 20%.

OPEN ACCESS AND THE EMERGENCE OF A COMPETITIVE NATURAL GAS MARKET

Recent regulatory changes permitted natural gas pipelines to become "open access" transporters. This change in pipeline carrier status dissolved regulatory barriers to markets. This paper describes the institutions that were developed to support exchange in gas markets and observes and evaluates their emergence, evolution, and performance. The institutional and empirical evidence reveals that gas markets rapidly emerged with the dissolution of regulatory barriers. Spot gas prices converged and became highly correlated. A national market for natural gas developed within four years.     

MEASURING THE PRICE OF RESEARCH AND DEVELOPMENT OUTPUT

We construct a price index for the scientific R&D services industry, a significant producer of R&D in the United States. Unlike most previous R&D price indexes, our index is not based on input costs but rather on measures of R&D sales. Consequently, unlike input‐cost price indexes, our output‐based index is able to account for changes in productivity and markups in the scientific R&D services industry. We compute that scientific R&D services prices increased, on average, by 7.14 percent at an annual rate from 1987 to 2006. Using our index, we find that real revenues grew at an annual average rate of 2.85 percent. We then propose using our index, in combination with an input‐cost price index, to deflate total R&D nominal expenditures. We find that real total U.S. R&D expenditures grew at an average annual rate of 1.42 percent from 1987 to 2006.     

The Law of One Price: A Canada/U.S. exploration

The paper examines whether arbitrage tends to equalize commodity prices for internationally traded homogenous products. It also investigates whether the increasing integration of North American markets has reduced price differences over time, and tests the validity of the so-called Law of One Price. We find that price differences for homogenous tradables between Canada and the U.S. are smaller than those for differentiated tradables and non-tradables, and are statistically insignificant over the period 1985 to 1999. We find no support for the notion that the increasing integration of North American markets due to trade liberalization has reduced price differences between Canada and the United States. Instead, the shifts in the price differences (expressed in the same currency) generally reflected fluctuations in the exchange rate. Canadian prices adapt with a lag to U.S. price changes that are brought about by changes in the exchange rate.     

Information in stock prices: the case of the 2016 U.S. presidential election

On the day before the 2016 U.S. presidential election, the odds of Hillary Clinton winning the presidency, according to political prediction markets, were above 90%. Surprisingly, Donald Trump won the Electoral College handily. In this study, we examine how movements in specific stock prices foreshadowed the eventual outcome. Specifically, we conduct a series of standard event-study tests focused on pharmaceutical companies, which became a focal point during the presidential campaign. Results show that while stocks of pharmaceutical companies significantly underperformed the market prior to the election, prices substantially increased beginning three days before the election outcome. This increase is both statistically significant and economically meaningful and robust to various event-study methodologies. These results suggest that some sectors of the stock market seemed to anticipate the election outcome.     

The relationship between developed equity markets and the Pacific Basin's emerging equity markets

Using a trivariate vector autoregression (VAR) model with a proper control for heteroscedasticity, this paper investigates the relationships between the two largest equity markets in the world—the U.S. and Japan—and the four Asian emerging equity markets: Hong Kong, Korea, Singapore, and Taiwan. Evidence indicates that the links between the developed markets and the Asian emerging markets (AEMs) began to increase after the stock market crash in October 1987, and have significantly intensified since the outbreak of the Asian financial crisis in July 1997.
