How to Regulate Heterogeneous Hospitals?

In many areas of health care financing, there is controversy over the sources of cost variability and about the respective roles of inefficiency versus legitimate heterogeneity. This paper proposes a payment system that creates incentives to increase hospital efficiency when hospitals are heterogeneous, without reducing the quality of care. We consider an extension of Shleifer's yardstick competition model and apply an econometric approach to identify and evaluate observable and unobservable sources of cost heterogeneity. Moral hazard can be seen as the result of two components: long‐term moral hazard (hospital management can be permanently inefficient) and transitory moral hazard. The latter is linked to the manager's transitory cost‐reducing effort. For instance, he or she can be more or less rigorous each year when bargaining prices for supplies delivered to the hospital by outside firms. The use of a three‐dimensional nested database makes it possible to identify transitory moral hazard and to estimate its effect on hospital cost variability. Econometric estimates are performed on a sample of 7,314 stays for acute myocardial infarction observed in 36 French public hospitals over the period 1994–1997. We obtain two alternative payment systems. The first takes all unobservable hospital heterogeneity into account, provided that it is time invariant, whereas the second ignores unobservable heterogeneity. Simulations show that substantial budget savings—at least 20%—can be expected from the implementation of such payment rules. The first method of payment has the great advantage of reimbursing high‐quality care. It leads to substantial potential savings because it provides incentives to reduce costs linked to transitory moral hazard, whose influence on cost variability is far from negligible. This payment rule could be extended to other areas of health care financing, such as Adjusted Average Per Capita Cost to calculate Medicare Managed Care reimbursements in the United States.     

A quantitative study of financing efficiency of low‐carbon companies: A three‐stage data envelopment analysis

This study set out to evaluate the financing efficiency of low‐carbon companies. Applying a three‐stage data envelopment analysis with the data from 85 listed companies in China's low‐carbon industries over the period 2011 to 2017, this study has found that the overall financing efficiency of low‐carbon companies was relatively high, and the pure technical efficiency was quite steady over the period. The overall financing efficiency of these low‐carbon companies on average tended to change with the scale efficiency. This study has also shown that the scale efficiency was the main constraint influencing the financing efficiency of low‐carbon companies in China over the period. Our results are robust and have significant implications for policy makers and corporate managers.     

The Old‐Boy Network and the Quality of Entrepreneurs

We study a model of network formation and start‐up financing with endogenous entrepreneurial type distribution. A hub firm admits members to its network based on signals about entrepreneurs' types. Network membership is observable, which allows lenders to offer different interest rates to network and stand‐alone entrepreneurs. We show that a network outcome can display a smaller number of high‐type entrepreneurs even though the network is neither nepotistic nor informationally disadvantaged. Although a welfare‐improving network can emerge as a technically stable or unstable equilibrium, one that decreases welfare is always formed by a technically unstable equilibrium. However, the adverse welfare effects of a network and its corresponding type configuration may persist because ex post high‐type entrepreneurs prefer to stay high type whereas those who wish to become high type may need some time to react.     

Financial constraints and synergy gains from mergers and acquisitions

This paper examines mergers and acquisitions motivated by financial constraints. Synergy gain is measured as the cumulative abnormal return of a value‐weighted portfolio of the acquirer and the target around the acquisition announcement. By constructing a financial constraint difference between the target and the acquirer, we find a positive relationship between the financial constraint difference and synergy gains generated from the acquisition. The positive effect of the financial constraint difference is only significant for high growth targets and severely constrained targets. The acquirer's corporate governance also enhances the synergy gains created from the financial constraint difference. Additional evidence shows that both acquirer's and target's shareholders benefit from the financial constraint difference. Our results are robust for different measures of financial constraint.     

The Valuation of Management Control Systems in Start-Up Companies: International Field-Based Evidence

Abstract

The question of whether management control systems (MCSs) adopted by start-up companies are valuable is examined. We investigate an international sample of start-ups, including their detailed MCS adoptions and financing histories. We find that higher MCS intensity, which is measured as the number of systems adopted at year-end immediately prior to the financing round, has a positive impact on company value. We also find that equity financiers value MCS more than do debt financiers. The valuation implication is more pronounced for start-up companies operating in highly competitive environments and with higher growth. We also document a positive relation between change in MCS intensity and change in firm value. Additional analyses show that higher company valuation is found for companies that align their MCS choices with their strategic positioning. In particular, systems that implement strategy are perceived to be more important and valuable than others. Overall, our paper provides new evidence for the debate concerning the merits of formal control in start-up companies.

Competition Among Health Plans: A Two‐Sided Market Approach

We set up a two‐sided market framework to model competition between a Prefered Provider Organization (PPO) and a Health Maintenance Organization (HMO). Both health plans compete to attract policyholders on one side and providers on the other. The PPO, which is characterized by a higher diversity of providers, attracts riskier policyholders. Our two‐sided framework allows us to examine the consequences of this risk segmentation on the providers' side, especially in terms of remuneration. The outcome of the competition depends mainly on two effects: a demand effect, influenced by the value put by policyholders on the providers access and an adverse selection effect, captured by the characteristics of the health risk distribution. If the adverse selection effect is too strong, the HMO receives a higher profit in equilibrium. On the contrary, if the demand effect dominates, the PPO profit is higher in spite of the unfavorable risk segmentation. We believe that by highlighting the two‐sided market structure of the health plans' competition, our model provides a new insight to understand the increase in the PPOs' market share as observed in the USA during the last decade.     

A Computational Dynamic Model of Strategic Behavior in the US Retail Banking Market

This paper examines the dynamics of bank strategies and performance in retail deposit markets. I develop an infinite‐horizon computational dynamic equilibrium duopoly model of value‐maximizing banks. It is used to analyze several critical aspects of behavior in local banking markets such as price and non‐price competition, strategic interactions between small and large banks, de novo bank growth, and consumer switching. The results suggest that growing banks offer higher deposit interest rates than established banks. Established banks are more likely to engage in non‐price competition, which can impede the effectiveness of de novo bank strategies and growth. Copyright © 2015 John Wiley & Sons, Ltd.     

融资约束与企业并购——来自中国上市公司的经验证据

利用2010—2018年中国沪深A股上市公司的并购数据,采用Logistic回归和双重差分估计法研究融资约束对企业并购的事前选择效应及并购对目标方融资约束的事后处理效应。研究结果表明：（1）在融资能力方面具有优势的企业更有可能成为潜在的收购方,且其更偏好于收购融资约束程度与自身存在差异（高于自身）的中等规模企业;（2）并购后,目标方的融资约束程度总体上显著降低,但不同成长能力和所有权性质的企业存在异质性,对于非国有企业和成长能力较高的企业,并购带来的融资约束缓解效应更显著。研究结论表明,通过缓解目标方融资约束获得协同效应是企业并购的重要驱动力。     

公司管理层权力与银行信贷融资决策

运用中国上市公司2010—2013年相关数据,考察公司管理层权力与公司融资结构及银行信贷资源配置,结果显示：公司的管理层结构及高管层权力是公司融资政策选择和银行信贷资源配置的重要动因,公司管理层权力越大,管理层向银行借入短期借款越多,公司管理层权力与短期借款结构正相关。在债务约束效应下,管理层可能会出于个人任期和控制权私利的原因做出影响公司融资决策的行为,在公司银行信贷融资中表现为银行信贷融资规模与公司管理层权力呈现负相关关系,即管理层权力越大,公司配置的银行信贷资源越少;同时,公司管理层权力中结构权力与所有者权力对公司信贷决策有重要影响。     

Diasporas and Domestic Entrepreneurs: Evidence from the Indian Software Industry

This study explores the importance of cross‐border social networks for entrepreneurs in developing countries by examining ties between the Indian expatriate community and local entrepreneurs in India's software industry. We find that local entrepreneurs who have previously lived outside India rely significantly more on diaspora networks for business leads and financing. This is especially true for entrepreneurs who are based outside software hubs—where getting leads to new businesses and accessing finance is more difficult. Our results provide micro‐evidence consistent with a view that cross‐border social networks play an important role in helping entrepreneurs to circumvent the barriers arising from imperfect domestic institutions in developing countries.     

Does competition prevent industrial pollution? Evidence from a panel threshold model

The objective of this paper is to assess the impact of competition on industrial toxic pollution by using, for the first time, a panel threshold model which allows evaluations of the main drivers of toxic releases under two different market regimes. The empirical analysis is based on a micro‐level panel dataset over the five‐year period 1987–2012. We show that this relationship is statistically significant and robust above and below the threshold, even after accounting for alternative specifications of market concentration. Specifically, we unmask an inverted V‐shaped relationship between market concentration and industrial pollution. We argue that the increasing non‐parametric regression line up to a certain concentration (threshold) level indicates a negative effect on facilities' emissions levels, whereas a decreasing line indicates a positive effect. This relationship provides new insights into environmental policy design towards abatement of industrial releases and sustainability. Finally, our empirical model remains robust under different specifications properly accounted for possible endogeneity.     

Cash holding dynamics and competition intensity: Evidence from UK firms

Using a quasi-natural experiment and various measures of competition intensity, we examine whether an increase in product market competition is a key driver of firm cash holdings. We find that firms increase cash holdings when competition is intense. The results suggest that the degree of increase in cash holdings is magnified among firms exposed to high predatory threat and financing friction. In addition, we examine if increasing cash holdings offers a competitive advantage in the product market. Our results indicate that firms with large cash reserves make gains in market share at the expense of their rivals. Gains in the product market are more pronounced among firms with low exposure to predatory risk and financing frictions.     

The Dark Side of Deeply Meaningful Work: Work‐Relationship Turmoil and the Moderating Role of Occupational Value Homophily

How are close personal relationships experienced by people in deeply meaningful work? Drawing upon in‐depth interview data with 82 international aid workers, I offer three distinct contributions. First, I find that people who experience their work as deeply meaningful have high work devotion. I identify boundary inhibition as a mechanism to explain why they participate more willingly in overwork and erratic work, despite giving rise to time‐ and trust‐based conflict in their relationships. Second, I find that people with high work devotion often also experience emotional distance in their personal relationships when their close others don’t value their work – a context I call occupational value heterophily. This disconnection‐based conflict compounds the time‐ and trust‐based conflict and engenders an emotionally agonizing situation, which I call work‐relationship turmoil. Third, when close others do value their partner’s work – a context I call occupational value homophily – it fosters an emotional connection and offers an avenue for work‐relationship enrichment. These findings draw upon deeply meaningful work to detail the multi‐faceted work‐relationship experience among those with high work devotion.     

Asset specificity,capital intensity and capital structure: An empirical test

Capital investment and capital financing decisions interact. To resolve current controversies in investment-leverage-growth relationships requires an integrated industrial organization/financial economics empirical model of profit margins, capital investment intensity, leverage and risk. Using cumulative future losses in discontinued operations to measure the asset specificity of the firm's investments, empiricai results support a complementary (positive) relationship between debt and investment, the debt financing of verifiable contemporaneous growth, equity financing of future growth and the debt financing of specific assets. This evidence rejects the transactions cost theory of capital structure in Fortune 500 firms.     

TACKLING FALSE POSITIVES IN BUSINESS RESEARCH: A STATISTICAL TOOLBOX WITH APPLICATIONS

Serious concerns have been raised that false positive findings are widespread in empirical research in business disciplines. This is largely because researchers almost exclusively adopt the ‘p‐value less than 0.05’ criterion for statistical significance; and they are often not fully aware of large‐sample biases which can potentially mislead their research outcomes. This paper proposes that a statistical toolbox (rather than a single hammer) be used in empirical research, which offers researchers a range of statistical instruments, including a range of alternatives to the p‐value criterion such as the Bayesian methods, optimal significance level, sample size selection, equivalence testing and exploratory data analyses. It is found that the positive results obtained under the p‐value criterion cannot stand, when the toolbox is applied to three notable studies in finance.     

When Necessity Becomes a Virtue: The Effect of Product Market Competition on Corporate Social Responsibility

We test whether Corporate Social Responsibility (CSR) is driven by strategic considerations by empirically studying the link between competition and firms' social performance. We find that firms in more competitive industries have better social ratings. In particular, we show that (i) different market concentration proxies are negatively related to widely used CSR measures; (ii) that an increase in competition due to higher import penetration leads to superior CSR performance; (iii) that firms in more competitive environments have a superior environmental performance, measured by firm pollution levels; and (iv) that more product competition is associated to a larger within‐industry CSR variance. We interpret these results as evidence that CSR is strategically chosen.     

Cartel Detection in Procurement Markets

Cartel detection is usually viewed as a key task of either competition authorities or compliance officials in firms with an elevated risk of cartelization. We argue that customers of hard‐core cartels can have both incentives and possibilities to detect such agreements on their own initiative through the use of market‐specific datasets. We apply a unique dataset of about 340,000 market transactions from 36 smaller and larger customers of German cement producers and show that a price screen would have allowed particularly larger customers to detect the upstream cement cartel before the competition authority.

From constrained optimization to constrained dynamics: extending analogies between economics and mechanics

Economic equilibrium models have been inspired by analogies to stationary states in classical mechanics. To extend these mathematical analogies from constrained optimization to constrained dynamics, we formalize economic (constraint) forces and economic power in analogy to physical (constraint) forces and the reciprocal value of mass. Agents employ forces to change economic variables according to their desire and their power to assert their interest. These ex-ante forces are completed by constraint forces from unanticipated system constraints to yield the ex-post dynamics. The differential-algebraic equation framework seeks to overcome some restrictions inherent to the optimization approach and to provide an out-of-equilibrium foundation for general equilibrium models. We transform a static Edgeworth box exchange model into a dynamic model with procedural rationality (gradient climbing) and slow price adaptation, and discuss advantages, caveats, and possible extensions of the modeling framework.

     

Is environmental innovation conducive to corporate financing? The moderating role of advertising expenditures

Environmental innovation is an important way for firms to achieve sustainable development and acquire resources. Based on the stakeholder, resource dependence, and signal transmission theories, this study divided environmental innovation into substantive and strategic eco‐innovation and constructed a relationship model among environmental innovation, advertising expenditures, and corporate financing. Selecting 162 Chinese manufacturing listed companies from 2012 to 2017 as the research sample and adopting the multiple regression analysis method, the study found that substantive eco‐innovation had a positive effect on corporate financing, but strategic eco‐innovation had a significant negative effect on corporate financing. Further, advertising expenditures played a positive moderating role between substantive eco‐innovation, strategic eco‐innovation, and corporate financing. The robustness test further confirmed these results.
