We develop a model that examines the capital structure and investment decisions of regulated firms in a setting that incorporates two key institutional features of the public utilities sector in many countries: firms are partially owned by the state and regulators are not necessarily...

We develop a model of portfolio choice to nest the views of Keynes - who advocates concentration in a few familiar assets - and Markowitz - who advocates diversification across assets. We rely on the concepts of ambiguity and ambiguity aversion to formalize the idea of an investor’s...

Credit constraints are more frequent among growth companies with large investment opportunities. For the same reason, profit taxes may harm innovative firms more than standard ones. This paper develops a model of heterogeneous firms where an endogenous share opts for innovation and faces credit...

We conduct the first systematic evaluation of the world’s largest community-based development program--China’s flagship poverty alleviation program began in 2001 which finances public investments in designated poor villages based on participatory village planning. We use matching methods and...

Using a general two-stage framework, this paper gives sufficient conditions for increasing competition to have negative or positive effects on R&D-investment, respectively. Both possibilities arise in plausible situations, even if one uses relatively narrow definitions of increasing competition....

Before the crisis, there were strong arguments for reducing global imbalances. As a result of the crisis, there have been significant changes in saving and investment patterns across the world and imbalances have narrowed considerably. Does this mean that imbalances are a problem of the past?...

Whether or not the marginal product of capital (MPK) differs across countries is a question that keeps coming up in discussions of comparative economic development and patterns of capital flows. Attempts to provide an empirical answer to this question have so far been mostly indirect and based...

We revisit the debt overhang question. We first use non-parametric techniques to isolate a panel of countries on the downward sloping section of a debt Laffer curve. In particular, overhang countries are ones where a threshold level of debt is reached in sample, beyond which (initial) debt ends...

Underdevelopment is thought to be about lack of investment, and many political economy theories can account for this. Yet, there has been much investment in developing countries. The problem has been that investment growth has not led to output growth. We therefore need to explain not simply...

This paper investigates the determinants of vertical integration. We first derive a number of predictions regarding the relationship between technology intensity and vertical integration from a simple incomplete contracts model. Then, we investigate these predictions using plant-level data for...
