Information gathering is an instinctive response to uncertainty, but such efforts may not fully resolve the uncertainty that prompted them. This implies that proxies for investor information gathering may endogenously reflect investor uncertainty, not only before but also after information...

Integrated ownership is often seen as a way to foster specific investments. However, even in integrated firms, managers invest to maximize their compensation, which is chiefly driven by divisional income. Thus it is not clear that integration has any effect on investments in a world of...

This paper hypothesizes that if an earnings announcement fails to resolve uncertainty about the firm’s future outcomes, then management will take steps to further inform investors. The novelty of our approach consists of our empirical proxy for unresolved uncertainty, constructed using a...

The impact of uncertainty on firms' investment outlays is subject to an ongoing debate. Theory identifies several channels. Irreversibility, financing constraints and risk aversion make a negative relationship between uncertainty and investment likely. On the other hand, the ability of firms to...

This paper addresses optimal taxation, when the relationship between consumption and environmental damage is uncertain and treated as a random variable by policy makers. The main purpose is to analyze how additional uncertainty about this relationship affects the optimal unit tax on the...

This paper estimates the impact on the US economy of four types of uncertainty about (i) government spending, (ii) tax changes, (iii) public debt sustainability and (iv) monetary policy. Following a one standard deviation shock, uncertainty about debt sustainability has the largest and most...

The behaviour of future policy-makers substantially influences future greenhouse gas emissions. Uncertainty about the motives of future policy-makers may thus strongly influence the climate policy strategies of current policy-makers. Analytical and numerical analyses in this paper confirm this...

High income risk is part of life in developing countries. Climatic risks, economic fluctuations, but also a large number of individual-specific shocks make these households vulnerable to serious hardship. For example, details are given on the various shocks and events causing serious hardship to...

The standard method of testing for efficient risk-sharing in village economies does not allow one to identify vulnerable households, only to make statements about the average risk in the village, or of sub-groups identifiable on the basis of observables. Here, by working directly with...

This paper examines how cooperation in an insurance game depends on risk preferences and the riskiness of income. It considers a dynamic game where commitment is limited, and characterizes the level of cooperation as measured by the reciprocal of the discount factor above which perfect risk...
