A Markov‐perfect equilibrium model of the impacts of price controls on the performance of the pharmaceutical industry

I introduce a computable dynamic equilibrium model of the pharmaceutical industry, parameterize it using industry facts, and use it to predict what happens if the United States adopts price controls or one or more non‐U.S. countries abandon their controls. The model generates implications for firm value, research and development (R&D), the flow of new drugs, and consumer welfare. I highlight the sensitivity of the results to alternative assumptions about R&D costs, market size, technological opportunities, consumer heterogeneity, the extent to which choices internalize prices, barriers to entry in R&D, the extent to which R&D outcomes are correlated, and the nature of the controls.

基于2012—2020年先进制造业行业面板数据,运用系统GMM和门槛面板模型考察环境规制对绿色技术创新的影响及其传导机制,同时检验不同研发投入水平下环境规制对绿色技术创新的作用。结果显示：环境规制通过成本遵循和创新补偿两个渠道对先进制造业绿色工艺创新具有正向促进作用,而对绿色产品创新产生负向影响。研发投入在环境规制对先进制造业绿色技术创新的影响中存在双重门槛效应,在较高研发投入水平下,环境规制能够显著促进先进制造业绿色技术创新。     

The impact of costly regulation on R&D investment levels and productivity

Prior research finds that risk-taking has declined after the Sarbanes-Oxley Act of 2002, consistent with the notion that SOX's corporate governance and internal control mandates diverted resources away from corporate risk-taking. We introduce to the accounting literature a new measure of R&D productivity, Research Quotient, to examine whether SOX affects R&D risk-taking and R&D productivity differently and whether the quality of the firm's governance and internal controls, pre-SOX, moderate these relations. While we find the relation between SOX and R&D risk-taking is sensitive to research design choices, we find a consistent positive relation between SOX and Research Quotient. Our evidence indicates that while firms may allocate fewer resources to R&D post-SOX, they concurrently manage their R&D investments more productively. Further, our results are robust to a difference-in-difference design and are stronger for firms with weaker governance pre-SOX.     

The Impact of Strategic Investment Choices on Post-Issue Operating Performance and Survival of US IPO Firms

Abstract:  We examine the impact of strategic investment choices at the time of the IPO on: (i) the post-issue operating performance and (ii) the likelihood of failure and time-to-failure of newly public US firms. Our post-issue operating performance analysis uses various performance metrics, benchmarks, and expectation models. Overall, our evidence indicates that the extent of diversification and industry-adjusted capital expenditures intensity are generally positively related to changes in operating performance. We do not, however, document a consistent relation between industry-adjusted R&D expenditures and changes in operating performance. The results from our survival analysis suggest that pre-issue managerial commitment to R&D spending and developing diversified product lines enhance the ability of IPO issuing firms to remain viable for longer periods of time. Our study highlights the impact of various managerial investment decisions on the subsequent performance of newly public firms.     

Investment policy in family controlled firms

We explore the relation between family ownership and corporate investment policy. Our analysis centers on two incentives, risk aversion and extended investment horizons, which potentially influence the level and type of investments that family firms undertake. We find that family firms devote less capital to long-term investments than firms with diffuse ownership structures. When dividing long-term investment into its two components of R&D and capital expenditures, we note that family firms, relative to nonfamily firms, prefer investing in physical assets relative to riskier R&D projects. Additional tests indicate that family firms receive fewer patent citations per dollar of R&D investment relative to nonfamily firms. Overall, all empirical results indicate that family preferences for lower firm risk, across all family sub-types, affects corporate R&D spending and capital expenditures.     

R&D capitalization and audit fees: Evidence from China

Our study investigates the association between capitalized R&D costs and audit fees and whether this association reflects the effect of earnings management. By exploring Chinese listed firms, we find that capitalized R&D costs are positively associated with audit fees, where such positive association holds for both the discretionary and nondiscretionary portions of capitalized R&D costs. Moreover, the positive association between the discretionary portion of capitalized R&D costs and audit fees is more pronounced for firms with stronger incentives to manipulate earnings. Overall, our findings imply that firms' reporting incentives affect how auditors react to clients' accounting choices. This in turn suggests that auditors believe some firms capitalize R&D to manipulate earnings, and the resulting earnings-management concerns lead them to charge higher fees.     

Estimating dynamic R&D choice: an analysis of costs and long‐run benefits

This article estimates a dynamic structural model of discrete Research and Development (R&D) investment and quantifies its cost and long‐run benefit for German manufacturing firms. The model incorporates linkages between R&D choice, product and process innovations, and future productivity and profits. The long‐run payoff to R&D is the proportional difference in expected firm value generated by the investment. It increases firm value by 6.7% for the median firm in high‐tech industries but only 2.8% in low‐tech industries. Simulations show that reductions in maintenance costs of innovation significantly raise investment rates and productivity, whereas reductions in startup costs have little effect.     

Pairing provision price and default remedy: optimal two‐stage procurement with private R&D efficiency

This article studies cost‐minimizing two‐stage procurement with Research and Development (R&D). The principal wishes to procure a product from an agent. At the first stage, the agent can conduct R&D to discover a more cost‐efficient production technology. First‐stage R&D efficiency and effort and the realized second‐stage production cost are the agent's private information. The optimal two‐stage mechanism is implemented by a menu of single‐stage contracts, each specifying a fixed provision price and remedy paid by a defaulting agent. A higher delivery price is paired with a higher default remedy, and a more efficient type opts for a higher price and higher remedy.     

Environmental Product Standards, International Trade and Monopolistic Competition

Thispaper examines the performance of non-cooperative environmentalpolicy in the case of local consumption externalities. In a two-countrymodel with monopolistic competiton, governments simultaneouslyimpose environmental product standards. Stricter regulationsforce the industrial sector to shift resources from non-environmentalto environmental R&D. Since the R&Dallocation in each country depends on the domestic as well asforeign policy, local decisions affect the economic and ecologicalsystem in the other region. Despite the arising spillovers, thepayoff dominant equilibria of the countries' game are efficient.This result requires similar but not identical preferences andtechnologies in both countries. It holds even if the regionsdiffer in market size. Under certain conditions, the non-cooperativesolutions remain efficient in the case of global pollution.     

Spatial competition in retail markets: movie theaters

Retail markets are extremely important, but economists have few practical tools for analyzing the way dispersed buyers and sellers affect the properties of markets. I develop an econometric model of retail demand in which products are location specific and consumers have preferences over both geographic proximity and other store and product characteristics. The model uses data on the observed geographic distribution of consumers within a market to (1) help explain observed variation in market shares and (2) affect predicted substitution patterns between stores. Using data from the U.S. cinema industry, I use the estimated model to evaluate the form of consumer transport costs, the effect of a theater's price and quality choices on rivals, the effects of geographic differentiation, and the nature and extent of market power.     

The Determinants of Investor Valuation of R&D Expenditure in the Software Industry

This paper examines the cross-sectional variability in the market valuation of R&D expenditures in the pre-packaged computer software industry. Consistent with some prior research, this paper argues that R&D spending is valued heterogeneously by the stock market, and derives hypotheses regarding the determinants of the cross-sectional heterogeneity in the market valuation of R&D. The empirical tests use an extensive database containing product level information of software firms between 1994 and 1998, along with accounting and stock price data of the same period. The test results, consistent with our hypotheses, show that R&D spending is more valuable for firms with larger market shares, higher percentage of technical employees, and those that have diversified into different product categories. The results also indicate that market valuation of R&D spending is a function of product life cycle.     

Executive risk incentives,product market competition,and R&D

Prior studies have examined the relation between product market competition (PMC) and research and development (R&D) investments, while the impact of executive risk incentives on this relation remains unexplored. In this study, we find that Vega (the sensitivity of executives’ wealth to stock return volatility) weakens the negative relation between PMC and R&D. We also find that Vega strengthens the negative relation between PMC and firm performance when R&D investments grow higher. In sum, our results suggest that high‐Vega compensation portfolios in competitive environments may induce executives to overinvest in R&D projects, therefore hurting firm performance.     

产品与技术双重竞争下企业创新投资决策的实证研究

基于当前市场竞争新特征与新形式,通过构建技术竞争指标,将市场竞争的视角由单一的产品层面拓展到产品、技术双重角度,探讨这两类竞争对我国企业R&D投资的影响。结果表明：产品竞争、技术竞争对企业R&D投资都有正向促进作用,且控制产品竞争后,技术竞争的作用依然显著。进一步研究发现：与一般企业相比,高科技企业中产品竞争对R&D投资的促进作用会减弱,但技术竞争对R&D投资的促进作用会加强。同时,面临融资约束的企业由于资金不足,产品竞争、技术竞争对R&D投资的促进作用均会减弱。     

R&D investment and distress risk

This paper proposes that besides volatility, R&D can increase firms' distress risk through another channel. Unlike capital investment, R&D is more inflexible and subject to high adjustment costs. Moreover, R&D intensive firms face severe financial constraints and are more likely to suspend/discontinue R&D projects. Therefore, firms' distress risk increases with their R&D intensity. Using a large panel of US companies over the 1980 to 2011 period, I find a robust empirical relation between R&D and distress risk, primarily among financially constrained firms. Moreover, the effect of R&D on distress risk is magnified during economic downturns. I also find that firms that have been previously successful in R&D or firms with high analyst coverage can mitigate the relationship between R&D and distress risk.     

R&D expenditures and implied equity risk premiums

This study investigates the relationship between research and development (R&D) expenditures and risk premiums implied in the costs of equity capital. We posit that R&D expenditures represent an information risk factor resulting from both information asymmetry about R&D between investors and managers and low-quality R&D reporting that impairs the coordination between investors and managers with respect to managers’ investment decisions. Our results support our position by showing a positive association between R&D expenditures and implied equity risk premiums. From this research along with prior studies, investors can have better knowledge about the risky nature of R&D expenditures that drive up implied risk premiums and at the same time provide opportunities to earn excess returns in a short to long horizon. Accounting standard setters can benefit from this study’s findings that R&D expenditures represent an off-balance-sheet risk factor and thus warrant reconsidering SFAS No. 2 for potential capitalization of R&D expenditures.     

Managerial incentives and risk-taking

We provide empirical evidence of a strong causal relation between managerial compensation and investment policy, debt policy, and firm risk. Controlling for CEO pay-performance sensitivity (delta) and the feedback effects of firm policy and risk on the managerial compensation scheme, we find that higher sensitivity of CEO wealth to stock volatility (vega) implements riskier policy choices, including relatively more investment in R&D, less investment in PPE, more focus, and higher leverage. We also find that riskier policy choices generally lead to compensation structures with higher vega and lower delta. Stock-return volatility has a positive effect on both vega and delta.     

研发投入、冗余资源与企业绩效的关系研究

采用创业板企业2010～2014年数据为研究对象,实证分析研发投入与企业绩效的关系,探讨冗余资源对于二者关系的调节效应.结果表明,我国创业板企业研发投入强度与当期绩效显著负相关,而与滞后一至三期企业绩效显著正相关.考虑企业冗余资源的影响,进一步研究发现,沉淀性冗余资源和非沉淀性冗余资源对研发投入强度与企业绩效的关系分别具有负向和正向的调节效应,说明沉淀性冗余资源不利于企业研发绩效的提升,而非沉淀性冗余资源则可以有效促进企业进行创新研发,提高研发效率,最终提升企业绩效.     

Public entrants,public equity finance and creative destruction

We explore the importance of new public firms and public equity finance for R&D and creative destruction in the US high-tech sector. Over 1900 new public firms enter high-tech manufacturing between 1970 and 2004; they are increasingly R&D intensive and rely extensively on public equity finance in the 1980s and 1990s. We estimate dynamic R&D models and find a strong link between public equity finance and R&D for new entrants, but not established entrants or incumbents. Further, recent cohorts of public entrants have a substantial economic impact: by 2000, recent public entrants account for almost half of high-tech sales and more than half of R&D. Variation in the availability of public equity finance has a marked impact on entrant R&D and the rate at which entrants take market share from incumbents. Our findings identify a key channel through which public equity markets facilitate the process of creative destruction.
