Aghion P, Burgess R, Redding S, Zilibotti F. Entry Liberalization and Inequality in Industrial Performance. 2004.Abstract

Industrial delicensing which began in 1985 in India marked a discrete break from a past of centrally planned industrial development. Similar liberalization episodes are taking place across the globe. We develop a simple Schumpeterian growth model to understand how Örms respond to the entry threat imposed by liberalization. The model emphasises that Örm responses, even within the same industrial sector, are likely to be heterogeneous leading to an increase in within industry inequality. Technologically advanced Örms and those located in regions with pro-business institutions are more likely to respond to the threat of entry by investing in new technologies and production processes. Empirical analysis using a panel of 3-digit state-industry data from India for the period 1980-1997 conÖrms that delicensing led to an increase in within industry inequality in industrial performance.

Aghion P, Alesina A, Trebbi F. Endogenous Political Institutions. Quarterly Journal of Economics. 2004.Abstract

Political institutions influence economic policy, but they are themselves endogenous since they are chosen, in some way, by members of the polity. An important aspect of institutional design is how much society chooses to delegate unchecked power to its leaders. If, once elected, a leader cannot be restrained, society runs the risk of a tyranny of the majority if not the tyranny of a dictator. If a leader faces too many ex post checks and balances, legislative action is too often blocked. As our critical constitutional choice we focus upon the size of the minority needed to block legislation, or conversely the size of the (super)majority needed to govern. We analyze both “optimal” constitutional design and ”positive” aspects of this process. We derive several empirical implications which we then discuss.

Aghion P, Acemoglu D, Zilibotti F. Vertical Integration and Distance to Frontier. Journal of the European Economic Association, Papers and Proceedings. 2003.Abstract

We construct a model where the equilibrium organization of firms changes as an economy approaches the world technology frontier. In vertically integrated firms, owners (managers) have to spend time both on production and innovation activities, and this creates managerial overload, and discourages innovation. Outsourcing of some production activities mitigates the managerial overload, but creates a holdup problem, causing some of the rents of the owners to be dissipated to the supplier. Far from the technology frontier, imitation activities are more important, and vertical integration is preferred. Closer to the frontier, the value of innovation increases, encouraging outsourcing.
