Entrepreneurship in Equilibrium
This paper compares the financing of new ventures in start-ups (entrepreneurship) and in established firms (intrapreneurship). Intrapreneurship allows established firms to use information on failed intrapreneurs to redeploy them into other jobs. By contrast, failed entrepreneurs must seek other jobs in an imperfectly informed external labor market. While this external labor market leads to ex post inefficient allocations, it provides entrepreneurs with high-powered incentives ex ante. We show that two types of equilibria can arise (and sometimes coexist). In a low entrepreneurship equilibrium, the market for failed entrepreneurs is thin, making internal labor markets and intrapreneurship particularly valuable. In a high entrepreneurship equilibrium, the active labor market reduces the value of internal labor markets and encourages entrepreneurship. We also show that there can be too little or too much entrepreneurial activity. There can be too little because entrepreneurs do not take into account their positive effect on the quality of the labor market. There can be too much because a high quality labor market is bad for entrepreneurial incentives.
Limits of arbitrage: the state of the theory
We survey theoretical developments in the literature on the limits of arbitrage. This literature investigates how costs faced by arbitrageurs can prevent them from eliminating mispricings and providing liquidity to other investors. Research in this area is currently evolving into a broader agenda emphasizing the role of financial institutions and agency frictions for asset prices. This research has the potential to explain so-called "market anomalies" and inform welfare and policy debates about asset markets. We begin with examples of demand shocks that generate mispricings, arguing that they can stem from behavioral or from institutional considerations. We next survey, and nest within a simple model, the following costs faced by arbitrageurs: (i) risk, both fundamental and non-fundamental, (ii) short-selling costs, (iii) leverage and margin constraints, and (iv) constraints on equity capital. We finally discuss implications for welfare and policy, and suggest directions for future research
The dynamics of financially constrained arbitrage
We develop a model of financially constrained arbitrage, and use it to study the dynamics of arbitrage capital, liquidity, and asset prices. Arbitrageurs exploit price discrepancies between assets traded in segmented markets, and in doing so provide liquidity to investors. A collateral constraint limits their positions as a function of capital. We show that the dynamics of arbitrage activity are self-correcting: following a shock that depletes arbitrage capital, profitability increases, and this allows capital to be gradually replenished. Spreads increase more and recover faster for more volatile trades, although arbitrageurs cut their positions in these trades the least. When arbitrage capital is more mobile across markets, liquidity in each market generally becomes less volatile, but the reverse may hold for aggregate liquidity because of mobility-induced contagion

Why higher takeover premia protect minority shareholders
Posttakeover moral hazard by the acquirer and free‐riding by the target shareholders lead the former to acquire as few sharcs as necessary to gain control. As moral hazard is most severe under such low ownership concentration, inefficiencies arise in successful takeovers. Moreover, share supply is shown to be upward‐sloping. Rules promoting ownership concentration limit both agency costs and the occurrence of takeovers. Furthermore, higher takeover premia induced by competition translate into higher ownership concen‐tration and are thus beneficial. Finally, one share‐one vote and simple majority are generally not optimal, and socially optimal rules need not emerge through private contracting
Agency conflicts in public and negotiated transfers of corporate control
We analyze control transfers in firms with a dominant minority blockholder and otherwise dispersed owners, and show that the transaction mode is important. Negotiated block trades preserve a low level of ownership concentration, inducing more inefficient extraction of private benefits. In contrast, public acquisitions increase ownership concentration, resulting in fewer private benefits and higher firm value. Within our model, the incumbent and new controlling party prefer to trade the block because of the dispersed shareholders' free-riding behavior. We also explore the regulatory implications of this agency problem and its impact on the terms of block trades
