Make-and-ally governance, where integrated firms develop new products internally while simultaneously collaborating on new product development with suppliers, is becoming increasingly common in knowledge-based industries. Yet, there is little theory or evidence to explain the prevalence of this governance mode. In this paper, we propose that, when downstream commercialization is concentrated relative to upstream product development, make-and-ally governance improves market performance of knowledge-based products and facilitates value capture for the integrated firm. Using data from the Korean TV drama industry, we find qualitative and quantitative evidence that collaborative development between network companies and independent production companies improves viewership ratings of TV dramas. The results suggest that make-and-ally governance is driven partly by efficiency and partly by market power considerations.

As an interesting but neglected governance mechanism of a firm’s subsidiaries, corporate headquarters managers often take a position in significant subsidiaries (“parent-subsidiary common manager” hereafter), either as the board member or the operations manager. These parent-subsidiary common managers have direct access to divisional information and, therefore, possess greater knowledge useful for them to identify tax opportunities and coordinate tax-motivated activities across business units. Using senior executives’ subsidiary positions disclosed in Chinese listed firms’ annual reports, we examine the impact of parent-subsidiary common managers on corporate tax planning and find a lower effective income tax rate for firms appointing common managers. Additional analyses show that the tax-avoiding effect of common managers is more pronounced for firms with more intangible assets, more related-party transactions involving subsidiaries, and more diversified business. Moreover, we find stronger effects for those common managers who take a position in economically significant subsidiaries or subsidiaries entitled to preferential tax treatments. The effect is also stronger when common managers work as operations managers of the subsidiaries. Collectively, our study is the first to analyze the appointment of parent-subsidiary common managers and to show the impact of such an appointment on corporate decisions.

The Origins and Real Effects of the Gender Gap: Evidence from CEOs’ Formative Years∗

CEOs allocate more investment capital to male than female division managers. Using data from individual Census records, we find that this gender gap is driven by CEOs who grew up in male-dominated families—those where the father was the only income earner and had more education than the mother. The gender gap also increases for CEOs who attended all-male high schools and grew up in neighborhoods with greater gender inequality. The effect of gender on capital budgeting introduces frictions and erodes investment efficiency. Overall, the gender gap originates in CEO preferences developed during formative years and produces significant real effects.

Disclosure, Competition, and Learning from Asset Prices

This paper studies the classic information-sharing problem in a duopoly setting in which firms learn information from a financial market. By disclosing information, a firm incurs a proprietary cost of losing competitive advantage to its rival firm but benefits from learning from a more informative asset market. Firms' disclosure decisions can exhibit strategic complementarity, which is strong enough to support both a disclosure equilibrium and a nondisclosure equilibrium. Allowing minimal learning from asset prices dramatically changes firms' disclosure behaviors: without learning from prices, firms do not disclose at all; but with minimal learning from prices, firms can almost fully disclose their information. Learning from asset prices benefits firms, consumers, and liquidity traders, but harms financial speculators.

Rationalizing Outcomes: Mental-Model-Guided Learning in Competitive Markets

This paper explores how competitive market interactions between agents with different mental models can lead to dysfunctional learning which can, in turn, have significant implications for an agent’s performance. We build a simulation model where two agents with different mental models about their demand environment compete over many periods, with the decisions of one period leading to market outcomes that are then used to recalibrate the mental models which, in turn, are used to make the decisions in the following period. Three model variants, exploring different mental models about the demand structure, the cost structure, and the market are studied. Dysfunctional learning occurs through dynamic mechanisms involving rationalization of observations within flexible mental models and misinterpretation of observations because of poor understanding of rival mental models. These mechanisms sometimes lead to distortion of an agent’s own initially correct mental model of the demand environment and to superior relative performance by the agent with an incorrect model of that environment. The insights from the models are used to interpret the ascension of GM over Ford in the late 1920’s, the slow adoption of radial tires in the U.S., and the rise of Nirma over incumbent Hindustan Lever in the Indian detergent market.

Accounting for tacit coordination

Tacit coordination is a pervasive aspect of accounting practice. This paper teases out insights on tacit coordination from existing scholarship, starting with studies of everyday life accounting, then turning to professional practice. It develops an understanding that, in the application of rules and accounting standards, in producing, framing, auditing and using statements, records, apologies or excuses, accounting practitioners tacitly coordinate towards the passing of accounts. This passing can be articulated in terms of structures, agencies and processes of tacit coordination involved in making accounting happen. The implications of this understanding of accounting practice and the importance of the wider domain of enquiry it is indicating are discussed with respect to the stewardship position of accounting professionals and to the further development of accounting theory. The paper identifies a need for broad-based forms of accounting theory to support accounting practitioners in the stewardship of silence and provide an antidote against the idea that any account, any slice of information, or any amount of ‘big data’, could speak for itself – or that it should.

Alpha Decay

Using a novel sample of professional asset managers, we document positive incremental alpha on newly purchased stocks that decays over twelve months. While managers are successful forecasters at these short-to-medium horizons, their average holding period is substantially longer (2.2 years). Both slow alpha decay and the horizon mismatch can be explained by strategic trading behavior. Managers accumulate positions gradually and unwind gradually once the alpha has run out; they trade more aggressively when the number of competitors and/or correlation among information signals is high, and do not increase trade size after unexpected capital flows. Alphas are lower when competition/correlation increases.

What is the Expected Return on a Stock?


Intervenant : Ian Martin

We derive a formula that expresses the expected return on a stock in terms of the risk-neutral variance of the market and the stock’s excess risk-neutral variance relative to the average stock. These quantities can be computed fromindex and stock option prices; the formula has no free parameters. We run panel regressions of realized stock returns onto risk-neutral variances, and find that the theory performs well at 6-month, 1-year, and 2-year forecasting horizons. The formula drives out beta, size, book-to-market and momentum, and outperforms a range of competitors in forecasting stock returns out of sample. Our results suggest that there is considerably more variation in expected returns, both over time and across stocks, than has previously been acknowledged.

“Processing the Future: Venture Project Evaluation at the American Research and Development Corporation (1946–1973)”

This chapter is an analysis of the project appraisal procedures in place at American Research and Development Corporation (ARD) between 1946 and 1973, under the management of Georges F. Doriot. It shows the importance of knowledge technologies and administrative procedures in the way the venture capital company dealt with uncertain futures. The origins of these knowledge practices are traced back to Georges F. Doriot’s own views on business, and more generally to the pragmatist movement in business administration, of which he was a member. The conduct of project appraisal at ARD is then observed directly, and this reveals its reliance on a rich set of knowledge and diagnostic techniques, as well as administrative procedures. These observations allow for a specification of the nature and role of imagination in the entrepreneurship and venture capital practices examined here—in particular, its close relationship with organized knowledge.

Sovereign credit risk and exchange rates: Evidence from CDS quanto spreads

Sovereign CDS quanto spreads { the difference between CDS premiums denominated in U.S. dollars and a foreign currency { tell us how fnancial markets view the interaction between a country's likelihood of default and associated currency devaluations (the twin Ds). A noarbitrage model applied to the term structure of quanto spreads can isolate the interaction between the twin Ds and gauge the associated risk premiums. We study countries in the Eurozone because their quanto spreads pertain to the same exchange rate and monetary policy, allowing us to link cross-sectional variation in their term structures to cross-country differences in fscal policies. The ratio of the risk-adjusted to the true default intensities is 2, on average. Conditional on the occurrence default, the true and risk-adjusted 1-wee probabilities of devaluation are 4% and 75%, respectively. The risk premium for the euro
devaluation in case of default exceeds the regular currency premium by up to 0.4% per week.
