Involuntary Unemployment in Diamond-Type Overlapping Generations Models

Thus far involuntary unemployment does not occur in Diamond-type Overlapping Generations models. In line with Keynesian macroeconomics, involuntary unemployment is traced back to aggregate demand failures. While macro-economists majority refers aggregate demand failures to sticky prices, a minority attributes lacking aggregate demand to not perfectly flexible aggregate investment. The chapter investigates how an independent aggregate investment function causes involuntary unemployment under perfectly flexible competitive wage and interest rates in a Diamond-type neoclassical growth model with public debt and human capital accumulation. Moreover, it is shown that a higher public debt to output ratio enhances output growth and reduces involuntary unemployment.

Investment as the opportunity cost of dividend signaling

We provide evidence that dividends signal sustainable earnings generated by assets-in-place for firms with weak investment opportunities. In the cross-section, both dividend levels and changes contain more earnings information among firms with weaker investment opportunities. Intertemporally, when aggregate investment opportunities in the economy are worse, dividend changes convey more earnings information. In contrast, dividends have a more negative association with investment spending for firms with strong growth options, as funding investment is a higher priority for those firms. Collectively, our findings suggest that dividends serve as a counter-signal, whereby additional information about investment opportunities give rise to signaling that is non-monotonic in firm quality.

Lumpy Investment, Business Cycles, and Stimulus Policy

I study the aggregate implications of micro-level lumpy investment in a model consistent with the empirical dynamics of the real interest rate. The elasticity of aggregate investment with respect to shocks is procyclical because more firms are likely to make an extensive margin investment in expansions than in recessions. Matching the dynamics of the real interest rate is key to generating this result because it disciplines the interest-elasticity of investment and avoids counterfactual behavior of the model that would otherwise eliminate most of the procyclical responsiveness. Therefore, data on interest rates place important discipline in aggregating micro-level investment behavior. (JEL D25, E13, E22, E23, E43, G31, H25)

Investment agreements and the fragmentation of firms across countries

We examine the global ownership structure of firms in the context of the investment regime. Investment agreements extend valuable privileges to firms invested abroad. But, these privileges only apply to firms whose assets are owned in a country that has signed an agreement with their host market; firms lack protections under investment agreements for many of their target markets. We argue that, by strategically locating subsidiaries in ‘transit’ countries, firms systematically expand their access to investment agreements. This firm-specific access to investment agreements through transit countries also has implications for investment flows: Transit countries receive more inflows and outflows of investment. Moreover, the impact of agreements declines over time and treaty partners, as seemingly newly protected firms have previously gained coverage through subsidiaries. Drawing on subsidiary location choices of the world’s largest firms, as well as data on firm ownership structures and aggregate investment flows, we present systematic evidence consistent with this argument. The paper highlights the importance of the global ownership structure of firms in an environment of heterogeneous international rules and discusses new distributional consequences of the investment regime.

Information Disclosure in Contests with Endogenous Entry: An Experiment

We use a laboratory experiment to study the effects of disclosing the number of active participants in contests with endogenous entry. At the first stage, potential participants decide whether to enter competition, and at the second stage, entrants choose their investments. In a 2[Formula: see text]2 design, we manipulate the size of the outside option, [Formula: see text], and whether the number of entrants is disclosed between the stages. Theory predicts more entry for lower [Formula: see text] and the levels of entry and aggregate investment to be independent of disclosure in all cases. We find empirical entry frequencies decreasing with [Formula: see text]. For aggregate investment, we find no effect of disclosure when [Formula: see text] is low but a strong positive effect of disclosure when [Formula: see text] is high. The difference is driven by substantial overinvestment in contests with a small, publicly known number of players contrasted by more restrained investment in contests in which the number of players is uncertain and may be small. The behavior under disclosure is explained by a combination of joy of winning and entry regret. This paper was accepted by Yan Chen, decision analysis.
