Managing the Performance Trade‐Offs from Partner Integration: Implications of Contract Choice in R&D Projects

Formal contracts represent an important governance instrument with which firms exercise control of and compensate partners in R&D projects. The specific type of contract used, however, can vary significantly across projects. In some, firms' govern partnering relationships through fixed‐price contracts, whereas in others, firms' use more flexible time and materials or performance‐based contracts. How do these choices affect the costs and benefits that arise from greater levels of partner integration? Furthermore, how are these relationships affected when the choice of contract is misaligned with the scope and objectives of the partnering relationship? Our study addresses these questions using data from 172 R&D projects that involve partners. We find that, (i) greater partner integration is associated with higher project costs for all contract types; (ii) greater partner integration is associated with higher product quality only in projects that adopt more flexible time and materials or performance‐based contracts; and (iii) in projects where the choice of contract is misaligned with the scope and objectives of the partnering relationship, greater partner integration is associated with higher project costs, but not with higher product quality. Our results shed light on the subtle interplay between formal and relational contracting. They have important implications for practice, with respect to designing optimal governance structures in partnered R&D projects.     

Earnings and Consumption Dynamics: A Nonlinear Panel Data Framework

We develop a new quantile‐based panel data framework to study the nature of income persistence and the transmission of income shocks to consumption. Log‐earnings are the sum of a general Markovian persistent component and a transitory innovation. The persistence of past shocks to earnings is allowed to vary according to the size and sign of the current shock. Consumption is modeled as an age‐dependent nonlinear function of assets, unobservable tastes, and the two earnings components. We establish the nonparametric identification of the nonlinear earnings process and of the consumption policy rule. Exploiting the enhanced consumption and asset data in recent waves of the Panel Study of Income Dynamics, we find that the earnings process features nonlinear persistence and conditional skewness. We confirm these results using population register data from Norway. We then show that the impact of earnings shocks varies substantially across earnings histories, and that this nonlinearity drives heterogeneous consumption responses. The framework provides new empirical measures of partial insurance in which the transmission of income shocks to consumption varies systematically with assets, the level of the shock, and the history of past shocks.     

MORAL HAZARD AND CAPITAL STRUCTURE DYNAMICS

We base a contracting theory for a startup firm on an agency model with observable but nonverifiable effort, and renegotiable contracts. Two essential restrictions on simple contracts are imposed: the entrepreneur must be given limited liability, and the investor's earnings must not decrease in the realized profit of the firm. All message game contracts with pure strategy equilibria (and no third parties) are considered. Within this class of contracts/equilibria, and regardless of who has the renegotiating bargaining power, debt and convertible debt maximize the entrepreneur's incentives to exert effort. These contracts are optimal if the entrepreneur has the bargaining power in renegotiation. If the investor has the bargaining power, the same is true unless debt induces excessive effort. In the latter case, a nondebt simple contract achieves efficiency—the noncontractibility of effort does not lower welfare. Thus, when the noncontractibility of effort matters, our results mirror typical capital structure dynamics: an early use of debt claims, followed by a switch to equity‐like claims.

AN INTERNATIONAL COMPARISON OF LIFETIME INEQUALITY: HOW CONTINENTAL EUROPE RESEMBLES NORTH AMERICA

We compare earnings inequality and mobility across the United States, Canada, France, Germany and the United Kingdom during the late 1990s. A flexible model of earnings dynamics that isolates positional mobility within a stable earnings distribution is estimated. Earnings trajectories are then simulated, and lifetime annuity value distributions are constructed. Earnings mobility and employment risk are found to be positively correlated with base‐year inequality. Taken together they produce more equalization in countries with high cross‐section inequality such that the countries in our sample have more similar lifetime inequality levels than cross‐section measures suggest.     

MORAL HAZARD AND DYNAMIC INSURANCE DATA

This paper exploits dynamic features of insurance contracts in the empirical analysis of moral hazard. We first show that experience rating implies negative occurrence dependence under moral hazard: individual claim intensities decrease with the number of past claims. We then show that dynamic insurance data allow to distinguish this moral‐hazard effect from dynamic selection on unobservables. We develop nonparametric tests and estimate a flexible parametric model. We find no evidence of moral hazard in French car insurance. Our analysis contributes to a recent literature based on static data that has problems distinguishing between moral hazard and selection and dealing with dynamic features of actual insurance contracts. Methodologically, this paper builds on and extends the literature on state dependence and heterogeneity in event‐history data. (JEL: D82, G22, C41, C14)     

HOW DO INFORMAL AGREEMENTS AND REVISION SHAPE CONTRACTUAL REFERENCE POINTS?

The notion of contracts as reference points provides the basis for a deeper understanding of important phenomena such as the employment contract, vertical integration, firm scope, authority, and delegation. Previous experiments lend support to this notion but they ignore realistic aspects of trading relationships such as informal agreements and ex‐post renegotiation or revision. Here we show that the central behavioral mechanism underlying contractual reference points is robust to such considerations. Our data reveal that informal agreements can mitigate the trade‐off between rigidity and flexibility but they do not fully resolve the problem of misaligned reference points. Our experiments also show that contract revision is a more nuanced process than the previous literature has recognized. We find, for example, that it is sometimes better for parties to write a simple (rigid) contract and then revise it ex post if needed, rather than to anticipate and include future contingencies in a (flexible) contract from the outset.     

Endogenous Contracts in Unionized Oligopoly

We study the endogenous determination of contracts in a unionized oligopoly and the welfare implications thereof. Alternative contracts specify the sequencing in the selection of R&D and wages. They can be classified as ‘fixed’ when the unions set wages before the firms make their R&D decisions or ‘floating’ when the sequencing of these choices is reversed. If the unions are highly employment‐oriented, we find that either all firm–union pairs choose floating‐wage contracts or both contract types may coexist depending on the degree of technological spillovers. However, when the unions have stronger preference over attaining a good wage deal, then it becomes very likely that fixed‐wage contracts will endogenously emerge because they can serve as an insurance device against oppor tunistic wage increases. Our welfare analysis suggests that welfare‐improving contracts may nevertheless not always arise in equilibrium.     

Persistent Private Information

This paper studies the design of optimal contracts in dynamic environments where agents have private information that is persistent. In particular, I focus on a continuous‐time version of a benchmark insurance problem where a risk‐averse agent would like to borrow from a risk‐neutral lender to stabilize his utility. The agent privately observes a persistent state variable, typically either income or a taste shock, and he makes reports to the principal. I give verifiable sufficient conditions showing that incentive‐compatible contracts can be written recursively, conditioning on the report and two additional state variables: the agent's promised utility and promised marginal utility of the private state. I then study two examples where the optimal contracts can be solved in closed form, showing how persistence alters the nature of the contract. Unlike the previous discrete‐time models with independent and identically distributed (i.i.d.) private information, the agent's consumption under the contract may grow over time. Furthermore, in my setting the efficiency losses due to private information increase with the persistence of the private information, and the distortions vanish as I approximate an i.i.d. environment.     

COLLATERAL CONSTRAINTS IN A MONETARY ECONOMY

This paper reviews the role of collateral constraints in transforming small monetary shocks into large persistent output fluctuations. We do this by introducing money in the heterogeneous‐agent real economy of Kiyotaki and Moore (1997). Money enters in a cash‐in‐advance constraint and money supply is managed via open‐market operations. We find that a monetary shock generates persistent movements in aggregate output, the amplitude of which depends upon whether or not debt contracts are indexed. If only nominal contracts are traded, money shocks can trigger large output fluctuations. In this case a money expansion triggers a boom, whereas money contractions generate recessions. In contrast, if contracts are indexed then amplification is not only smaller; it can also generate the reverse results. When the possibility of default and renegotiation is considered, the model can generate asymmetric business cycles with recessions milder than booms. Finally, monetary shocks generate a highly persistent dampening cycle rather than a smoothly declining deviation. (JEL: E32, E43, E44, E52)     

Risk Communication,Values Clarification,and Vaccination Decisions

Many health‐related decisions require choosing between two options, each with risks and benefits. When presented with such tradeoffs, people often make choices that fail to align with scientific evidence or with their own values. This study tested whether risk communication and values clarification methods could help parents and guardians make evidence‐based, values‐congruent decisions about children's influenza vaccinations. In 2013–2014 we conducted an online 2×2 factorial experiment in which a diverse sample of U.S. parents and guardians (n = 407) were randomly assigned to view either standard information about influenza vaccines or risk communication using absolute and incremental risk formats. Participants were then either presented or not presented with an interactive values clarification interface with constrained sliders and dynamic visual feedback. Participants randomized to the risk communication condition combined with the values clarification interface were more likely to indicate intentions to vaccinate (β = 2.10, t(399) = 2.63, p < 0.01). The effect was particularly notable among participants who had previously demonstrated less interest in having their children vaccinated against influenza (β = –2.14, t(399) = –2.06, p < 0.05). When assessing vaccination status reported by participants who agreed to participate in a follow‐up study six months later (n = 116), vaccination intentions significantly predicted vaccination status (OR = 1.66, 95%CI (1.13, 2.44), p < 0.05) and rates of informed choice (OR = 1.51, 95%CI (1.07, 2.13), p < 0.012), although there were no direct effects of experimental factors on vaccination rates. Qualitative analysis suggested that logistical barriers impeded immunization rates. Risk communication and values clarification methods may contribute to increased vaccination intentions, which may, in turn, predict vaccination status if logistical barriers are also addressed.     

AMBIVALENT INVESTMENT AND THE HOLD‐UP PROBLEM

In this paper we add to the foundations of incomplete contracting literature. We study the hold‐up problem with ambivalent investment, where investment benefits the investing party if ex post the right decision is undertaken but harms the investing party if the wrong decision is made. In this context, we show that the power of contracts to provide investment incentives depends on three factors: the commitment value of contracts, the amount of quasirents that the investing party can expect in the case of out‐of‐contract renegotiation, and the degree of ambivalence of investment. First, contracts provide first‐best investment incentives when parties can commit to a contract regardless of the type of investment. Second, with sufficiently ambivalent investment, if parties cannot commit not to renegotiate a contract and if the investing party's bargaining power is intermediate, contracts cannot improve investment incentives above those provided by no contract. In contrast, a simple buyer or seller option contract is optimal when the investing party's bargaining power is extreme. (JEL: D23, K12, L22)

盈余管理是管理人员运用判断改变财务报告以使自己获益的行为,它的存在有其内在的和外在的原因,会计信息不对称、应计制本身的内在特点是盈余管理得以存在的内在原因,而对会计信息监管不力、有关契约的不完善则是其存在的外在条件,盈余管理的动机反映了分红假设、债务契约和政治成本假设以及资本市场的需求压力。盈余管理尽管有一定的正面作用,但其负面作用也是不容忽视的,它损害了会计信息使用者的利益,对资本市场的发展存在不利影响,因而必须采取有效措施防止其滥用。简要论述了盈余管理的涵义、原因和动机、手法、后果之后,对如何防范盈余管理、提高盈余信息含量提出了若干建议。     

Do the Falling Earnings of Immigrants Apply to Self‐employed Immigrants?

It is well known that the earnings of recent cohorts of immigrant men have fallen further behind native‐born men. Using several years of Canadian Census data, this study finds that immigrants have turned to self‐employment at a much faster rate than the native born. In addition, the earnings gap between self‐employed immigrant and native‐born men has not grown with successive cohorts, but rather has followed a cyclical movement: narrowing at the peak, and widening in times of weaker economic activity. However, immigrants choosing self‐employment still face challenges, as their earnings are far below native‐born earnings, and convergence is a lengthy process.     

Supply Contract Design for Competing Heterogeneous Suppliers under Asymmetric Information

This study considers a supply chain with two heterogeneous suppliers and a common retailer whose type is either low‐volume or high‐volume. The retailer's type is unknown to the suppliers. The flexible supplier has a high variable cost and a low fixed cost, while the efficient supplier has a low variable cost and a high fixed cost. Each supplier offers the retailer a menu of contracts. The retailer chooses the contract that maximizes its expected profit. For this setting, we characterize the equilibrium contract menus offered by the suppliers to the retailer. We find that the equilibrium contract menus depend on which supplier–retailer match can generate the highest supply chain profit and on how much information rent the supplier may need to pay. An important feature of the equilibrium contract menus is that the contract assigned to the more profitable retailer will coordinate the supply chain, while the contract assigned to the less profitable retailer may not. In addition, in some circumstances, the flexible supplier may choose not to serve the high‐volume retailer, in order to avoid excessive information rent.     

ON‐THE‐JOB SEARCH AND MORAL HAZARD

We analyze the interaction between intertemporal incentive contracts and search frictions associated with on‐the‐job search. In our model, agency problems call for wage contracts with deferred compensation. At the same time workers do on‐the‐job search. Deferred compensation improves workers' incentives to exert effort but distorts their on‐the‐job search decisions. We show that deferred compensation is less attractive when the value to the worker–firm pair of on‐the‐job search is high. Moreover, the interplay between search frictions and wage contracts creates feedback effects. If firms in equilibrium use contracts with deferred compensation, fewer firms with vacancies enter the on‐the‐job search market, and this in turn reduces the distortions created by deferred compensation. These feedback effects between the incentive contracts used and the activity level in the search markets can lead to multiple equilibria: a low‐turnover equilibrium where firms use deferred compensation, and a high‐turnover equilibrium where they do not. Furthermore, the model predicts that firms are more likely to use deferred compensation when search frictions are high and when the gains from on‐the‐job search are small.     

Immigrants' Relative Earnings in Sweden — A Cohort Analysis

Abstract. This paper examines the earnings assimilation of immigrants in Sweden by applying a quantile regression approach on pooled data during the period 1990–99. Immigrants from Nordic and Western European countries have a smaller entry earnings disadvantage and slower rate of assimilation than other groups of immigrants. For some cohorts of immigrants from European countries the initial earnings disadvantage disappears after 15–20 years in Sweden, but as non‐European immigrants suffered from very large entry earnings disadvantages, their earnings will not catch up with the earnings of natives during their first 20 years in Sweden. More recent non‐European immigrant cohorts had a larger entry earnings disadvantage than previous ones. The immigration policy, discrimination, and the economic conditions may have contributed to the decline in the earnings assimilation of non‐European immigrants.     

国有企业管理者激励效应研究——基于管理者权力的解释

本文突出管理者权力在企业激励契约中的作用,对不同管理者权力下国有企业高层管理者货币性补偿与企业绩效的关系进行研究。通过理论与实证分析,我们发现,权力强大的管理者可以自己设计激励组合,在获取权力收益的同时实现高货币性补偿,并不需要盈余管理迎合董事会的激励要求;而权力较弱的管理者则更关注货币性补偿,只能通过盈余管理虚构利润,以达到薪酬考核的目的。     

The Optimal Income Taxation of Couples

This paper analyzes the general nonlinear optimal income tax for couples, a multidimensional screening problem. Each couple consists of a primary earner who always participates in the labor market, but makes an hours‐of‐work choice, and a secondary earner who chooses whether or not to work. If second‐earner participation is a signal of the couple being better (worse) off, we prove that optimal tax schemes display a positive tax (subsidy) on secondary earnings and that the tax (subsidy) on secondary earnings decreases with primary earnings and converges to zero asymptotically. We present calibrated microsimulations for the United Kingdom showing that decreasing tax rates on secondary earnings is quantitatively significant and consistent with actual income tax and transfer programs.     

Labour Market Flexibility,Human Resource Management and Corporate Performance

Labour market flexibility is often portrayed as a key to the competitive success of the UK and US economies. We surveyed several hundred firms in the UK, and using the resulting data (on over 200 manufacturing firms) this paper investigates the relationships between firms’ use of flexible work practices, human resource systems and industrial relations on the one hand, and corporate performance on the other hand. The results suggest that ‘low‐road’ practices – short‐term contracts, a lack of employer commitment to job security, low levels of training and low levels of human resource sophistication – are negatively correlated with corporate performance. In contrast, it is found that ‘high‐road’ work practices –‘high commitment’ organizations or ‘transformed’ workplaces – are positively correlated with good corporate performance. It is also found that human resource management practices are more likely to contribute to competitive success where they are introduced as a comprehensive package, or ‘bundle’ of practices. Significant interaction effects between human resource systems, trade unions and flexible work practices add further support to the bundling hypothesis.     

Early Career Mobility and Earnings Profiles of German Apprentices: Theory and Empirical Evidence

We investigate how apprenticeship training affects the early career mobility and earnings profiles of young apprentices in Germany. The heterogeneous quality and nature (whether general or firm specific) of training across firms is expected to be reflected in the post‐apprenticeship mobility and earning patterns of young workers. In this paper, we argue that a simple model of training and labour turnover can explain such patterns. Specifically, assuming that job changes are associated with a loss of accumulated firm‐specific skills, the model predicts that although movers initially experience a productivity loss, their earnings grow at a faster rate than those of stayers. As job changes become more costly the longer a worker stays with the training firm, later movers experience a larger reduction in their earnings compared with direct movers. Estimated selectivity‐corrected earnings equations for movers and stayers, based on data from the German Socioeconomic Panel (GSOEP), support the predictions of the model and highlight important differences in earnings profiles and mobility patterns by apprenticeship firm size.
