Is Radio Advertising a Distinct Local Market? An Empirical Analysis

The recent relaxation of regulations limiting the ability of an entity to own multiple radio stations has led to a dramatic increase in ownership concentration in local radio markets. As a result, the Department of Justice has, on several occasions, required limited divestiture of multiple station owners. Implicit in the agency's action is that radio advertising constitutes an antitrust market. Using the framework established by the Merger Guidelines, this paper evaluates whether or not radio advertising is a distinct local market by estimating an own-price elasticity of demand for radio advertising. Our results support the assertion that radio advertising is an antitrust market.     

How do institutional investors react to local shocks during a crisis? A test using the COVID-19 pandemic

We examine how institutional investors reacted to geographically dispersed local shocks during the early stages of the COVID-19 pandemic. A sample of real estate investment trusts (REITs) enables us to link two layers of geography: the locations of the assets in which the REITs were invested and the headquarters locations of institutional investors who owned REIT shares. We find that the institutional ownership of firms with an economic interest in the investors’ home markets declined more if those markets were heavily affected by the pandemic. In addition, the ownership responses to the COVID-19 shock were larger in those markets in which REITs had larger portfolio allocations and in markets that were home to the investors. Importantly, we find that nonpassive and short-term investors may have overreacted to the local shocks because their REIT portfolios subsequently underperformed relative to passive and long-term investors. Our study highlights the importance of geography in the formation of investors’ expectations during market crises.     

Estimating the performance effects of business groups in emerging markets

Business groups—confederations of legally independent firms—are ubiquitous in emerging economies, yet very little is known about their effects on the performance of affiliated firms. We conceive of business groups as responses to market failures and high transaction costs. In doing so, we develop hypotheses about the effects of group affiliation on firm profitability: affiliation could either boost or depress firm profitability, and members of a group are likely to earn rates of return similar to other members of the same group. Using a unique data set compiled largely from local sources, we test for these effects in 14 emerging markets: Argentina, Brazil, Chile, India, Indonesia, Israel, Mexico, Peru, the Philippines, South Africa, South Korea, Taiwan, Thailand, and Turkey. We find evidence that business groups indeed affect the broad patterns of economic performance in 12 of the markets we examine. Group affiliation appears to have as profound an effect on profitability as does industry membership, yet strategy scholars have a much clearer grasp of industries than of groups. Moreover, membership in a group raises the profitability of the average group member in several of the markets we examine. This runs contrary to the wisdom, conventional in advanced economies, that unrelated diversification depresses profitability. Overall, our findings suggest that the roots of sustained differences in profitability may vary across institutional contexts; conclusions drawn in one context may well not apply to another.

Price Signaling and Return Chasing: International Evidence from Maturing REIT Markets

This article examines the liquidity of international real estate securities across 10 markets over the period 1990–2015. We apply and compare results for four different measures of liquidity, and find that while liquidity has increased consistently, wide variations still exist across markets, with the United States and Japan in the lead. Our results also suggest that the introduction of local REIT regimes did not have any pervasive effects on stock liquidity. When we study the relationship between liquidity and returns, we document new and consistent evidence for international return chasing behavior, whose pattern is a function of local market efficiency, listed real estate market maturity and stock ownership dispersion. The introduction of REIT regimes seems to weaken the importance of extra performance over and above general equity returns as investors tend to allocate funds to real estate securities within real estate rather than equity portfolios.     

DO ROCKETS RISE FASTER AND FEATHERS FALL SLOWER IN AN ATMOSPHERE OF LOCAL MARKET POWER? EVIDENCE FROM THE RETAIL GASOLINE MARKET*

This study explores the possibility that local market power influences the observed asymmetric relationship between changes in wholesale gasoline costs and changes in retail gasoline prices. I exploit an original data set of weekly gas station prices in Southern California from September, 2002 to May, 2003, and take advantage of detailed station and local market level characteristics to determine the extent to which geographic and product differentiation influence price response asymmetry. I find that brand identity, proximity to rival stations and local market features and demographics each influence a station's predicted price‐response asymmetry.     

Ownership structure and innovation: An emerging market perspective

Considerable attention has been focused on the ways in which emerging market firms can obtain and mobilize the knowledge and resources required for innovation. Innovation is a particular challenge in emerging markets because of inadequate external institutions. In this study, we focus on the importance of ownership structure, and in particular on ownership type diversity and ownership concentration. Using transaction cost and agency theories embedded in an emerging market context, we argue that ownership structure provides an important mechanism by which firms can assemble and direct the resources necessary for innovation in the context of inadequate external institutions. Specifically, we hypothesize that ownership type diversity improves innovation performance and that increasing ownership concentration has the same effect, but only up to a point. Using a panel dataset of 487 and 475 Chinese listed companies during 2004–2005 and 2005–2006 respectively, we find supportive empirical evidence for our hypotheses. Our findings also suggest that ownership type diversity is a more important factor in explaining innovation performance than ownership concentration, although most of the extant literature focuses on the latter.     

Does Competition Lead to Agglomeration or Dispersion in EMR Vendor Decisions?

We examine hospital Electronic Medical Record (EMR) vendor adoption patterns and how they relate to hospital market structure. As in many network technology adoption decisions, hospitals face countervailing incentives to coordinate or differentiate in their choice of vendors. We find evidence of substantial agglomeration on EMR vendors, which increases as hospital markets become more competitive. These findings suggest that incentives to coordinate dominate incentives to differentiate overall, and the relative balance grows stronger in favor of coordination as markets become more competitive. Our findings also have important implications regarding antitrust policy. A potential downside of hospital consolidation—increased obstacles in information sharing due to vendor differentiation—should be taken into account in evaluation of hospital mergers.     

Corporate Governance and returns on information technology investment: evidence from an emerging market

Prior studies have reported mixed findings on the impact of corporate information technology (IT) investment on firm performance. This study investigates the effect of corporate governance, an important management control mechanism, on the relation between IT investment and firm performance in the Taiwanese electronics industry. Specifically, we explore board independence and foreign ownership, which have increasingly become salient factors concerning corporate governance in emerging markets. We address their roles across firms of different sizes and in industries where degrees of competitiveness run a wide gamut. Our results show a positive moderating effect of board independence on the IT investment‐firm performance relation, especially when competition intensifies. Furthermore, we find that the greater the foreign ownership in small firms, the more positive the IT investment‐firm performance relation, suggesting that foreign investors may bring IT expertise to help small firms reap the benefits of using IT.

The (low) power elite : Deregulated licensing criteria for low-power television in the USA

This article examines the policy context within which Low Power Television (LPTV) has developed in the USA, analysing the political, legal, aesthetic and technical considerations used to determine station ownership preferences among competing applicants. Although only a few LPTV stations are in commercial operation, the FCC has received over 32 000 applications from community, minority and commercial interest groups from every state. Unfortunately, this impressive growth potential has been stalled amidst debates concerning the constitutionality of various policy models governing station licensing and operation. At stake in the debate over who should own these outlets are myriad political, social and economic interests among public and private concerns vying for airspace. If the government allows corporate interests to compete against or challenge minority applicants, LPTV may follow the lead of VHF TV with respect to ownership concentration and programme content. Conversely, policies favouring community and minority applicants should promote innovative programme ideas featuring local talent, and address local issues.     

Do Substantial Horizontal Mergers Generate Significant Price Effects? Evidence From The Banking Industry

This study examines the price effects of recent US bank mergers that substantially increased local market concentration. Using the deposit interest rates that banks offer their customers as our price measure, we find that, over the 1991–94 time period, deposit rates offered by participants in substantial horizontal mergers and their local market rivals declined by a greater percentage than did deposit rates offered by banks not operating in markets in which such mergers took place. We interpret our results as evidence that these mergers led to increased market power.     

Regulation,enforcement, and entry: Evidence from the Spanish local TV industry

Although we have many tools to understand the effect of regulation on firm entry, we know little about the importance of actual regulation enforcement. For this purpose, this paper uses data from Spain's local television industry from 1995 through 2001, which provide a unique opportunity for examining how firms' profitability changes with the introduction of regulation and a posterior liberalization. During this period, the local television industry transitioned from a state of alegality (no regulation in place) to being highly regulated and finally to being informally deregulated. Using a firm entry model from Bresnahan and Reiss (1990, 1991a,b), we estimate local TV station entry thresholds by number of entrants across years. We find the entry threshold in 1998 increased relative to the thresholds in 1995 and 2001, suggesting that entry was less attractive during the period when the local TV industry was highly regulated. We decompose the entry thresholds into the fixed costs and variable profits, and find the fixed-cost ratios increase in 1998 and stay constant in 2001. Meanwhile, we find an increase in the variable-profit ratios in 2001. These findings suggest that the informal deregulation did not invalidate the regulation introduced in 1995 on the cost side. However, the deregulation seemed to have an impact on variable profits through how local TV stations competed.     

Mergers and product quality: Evidence from the airline industry

Retrospective studies of horizontal mergers have focused on their price effects, leaving the important question of how mergers affect product quality largely unanswered. This paper empirically investigates this issue for two recent airline mergers. Consistent with the theory that mergers facilitate coordination but diminish competitive pressure for quality improvement, we find that each merger is associated with a quality decrease (increase) in markets where the merging firms had (had no) pre-merger competition with each other, and the quality change can have a U-shaped relationship with pre-merger competition intensity. Consumer gains/losses associated with quality changes, which we monetize, are substantial.     

Retail Mergers and Food Prices: Evidence from France

This paper analyzes the impact of a merger in the French supermarket industry on food prices. Using consumer panel data, we compare the changes in prices for merging and rival firms in affected and comparison markets. We use a novel definition of affected markets when some firms have a local pricing strategy and others a more centralized pricing strategy. We find that prices increase significantly following the merger, and that the merging firms lose market shares. For the rivals, the price increases are larger in local markets, in which concentration increased and differentiation changed after the merger.     

ASYMMETRIC DYNAMIC PRICING IN A LOCAL GASOLINE RETAIL MARKET*

Asymmetric‐price adjustment is a common phenomenon in many markets around the world, particularly in retail gasoline markets. This paper studies the existence of this phenomenon in the retail gasoline market in the city of Santiago, Chile, using a data set of weekly gas station prices that covers a period of almost four years. We found that prices adjust asymmetrically, and the asymmetry is different for branded gas stations and unbranded stations. In addition, we found that the asymmetry for high‐margin stations is statistically equivalent to that for low‐margin stations. This evidence is suggestive of collusion as a rationale for the asymmetric pricing policy observed.     

The Effect of Corporate Governance on Investment: Evidence from Real Estate Investment Trusts

This study investigates the relation between firms' investment choices and various governance mechanisms, using a sample of real estate investment trusts (REITs). We find evidence that the responsiveness of REITs' investment expenditures to their opportunities depends on their corporate governance structures. Within the set of governance mechanisms that we examine, we find particularly strong links between investment behavior and ownership. Specifically, we find that the investment choices of REITs are more closely tied to Tobin's q if they have greater institutional ownership or if they have lower director and officer stock ownership. These results are consistent with institutional owners monitoring the firm's investment policies as well as with high insider ownership allowing managers to follow their own investment agendas.     

Local Energy Markets*

In current power markets, the bulk of electricity is sold wholesale and transported to consumers via long-distance transmission lines. Recently, decentralized local energy markets have evolved, often as isolated networks based on solar generation. We analyze strategic pricing, investment, and welfare in local energy markets. We show that local energy markets yield competitive equilibrium prices and provide efficient investment incentives. Yet, we find that strategic behavior leads to allocative inefficiency. We propose a clearing mechanism that induces truth-telling behavior and restores first-best welfare.     

Business group affiliation and firm performance in a transition economy: A focus on ownership voids

In a transition economy, how does business group affiliation make a difference in firm performance? Under the broad label of institutional voids, what specific voids can business groups fill? This paper addresses these questions by drawing on insights from property rights theory and an institutional perspective. We argue that ownership voids, as a subset of institutional voids, occur due to the lack of unambiguously specified ownership of state assets in transition economies, and that business groups emerge to serve as the direct owners of state-owned enterprises to replace such voids. Based on a sample of 1,119 publicly-listed Chinese companies, we find that the interaction of business group affiliation and state ownership has a significant and positive effect on firm performance. Our findings point to business group’s substitution role in filling ownership voids in China’s transition economy.     

Impact of state ownership and control mechanisms on the performance of group affiliated companies in China

This paper examines the moderating impact of state ownership and group control mechanisms on the relationship between diversification and performance of companies affiliated with large business groups in China. We find that the state ownership has enhanced the performance of group affiliated companies when they adopted higher degrees of diversification. We also find that cash flow rights have a positive impact on the performance of companies with lower degrees of diversification while in general group control rights have a negative impact on the performance. These results suggest that a group’s control mechanisms, derived from pyramid ownership structures, enable the dominant owners to expropriate the value from minority shareholders or tunnel corporate resources for their own interest.

The Effect of Explicit Communication on pricing: Evidence from the Collapse of a Gasoline Cartel

We study the collapse of collusion in Québec's retail gasoline market following a Competition Bureau investigation, and show that it involved two empirical regularities: high margins, and asymmetric price adjustments. Using weekly, station‐level prices we test whether collusion was successful, and whether asymmetric adjustments were part of the cartel's strategy. We do so in the markets targeted by the investigation, and in markets throughout the province with similar pre‐collapse pricing (cyclical markets). Our results suggest that stations in both target and cyclical markets adjusted pricing following the announcement: margins fell (by 30%/15% in target/cyclical markets), and adjustments became more symmetric.     

Business groups in developing capital markets: Towards a complementarity perspective

Prior research suggests that business groups (BGs) in developing economies have emerged as alternatives to poorly developed economic institutions in these countries. In this paper, we argue that this does not imply they are always substitutes. Specifically, we consider the case of capital markets, a key economic institution: while the absence of well‐developed capital markets may indeed have stimulated the emergence of business groups, we propose that BG affiliation and the scrutiny that maturing capital markets impose on firms that participate actively in them nevertheless can play a complementary role in influencing a firm's performance. We find support for our predictions in a novel longitudinal data set of Indian firms that contain both listed and unlisted BG affiliated as well as unaffiliated firms.
