Firms often give away free goods with the product that they sell. Firms often give stock options to their top management and other employees. Mixing these two practices-giving stock options to consumers who buy the firm's product-, creates a deadly brew. Large numbers of consumers can be lured...

We consider to what extent the empirical failings of the Q model of investment can be attributed to the use of share prices to measure average q. We show that the usual empirical formulation may fail to identify the Q model when stock market valuations deviate from the present value of expected...

We derive robust predictions on the effects of uncertainty on short run investment dynamics in a broad class of models with (partial) irreversibility. When their environment becomes more uncertain firms become more cautious and less responsive to demand shocks. This result contrasts with the...

We refine modelling of the radical innovation decision in this paper by extending real option theory to include non-marginal stochastic jump processes. From the model analytics we determine that the average magnitude and frequency of non-marginal stochastic jump processes are the most important...

In new new international trade theory, whether firms export or not are determined by their productivity. These models assume that firms enter a market to find their productivity levels revealed to them as in a lottery. In this paper we propose an alternative way to model whether firms export or...

Sharing is a norm in many societies. We present a theoretical model on the trade-off between sharing and investment which we test on data from tailors in Burkina Faso. The empirical results support the idea that there are two behavioural patterns: entrepreneurs following an 'insurance regime'...

This paper contributes to the empirical literature on the relationship between environmental regulation and firm behavior. In particular, we ask whether and how strongly an industry's investment responds to stringency in environmental regulation. Environmental stringency is measured as (i) an...

The objective of this paper is to combine a real options framework with portfolio optimization techniques and to apply this new framework to investments in the electricity sector. In particular, a real options model is used to assess the adoption decision of particular technologies under...

This paper contributes to the empirical literature on the relationship between environmental regulation and firm behavior. In particular, we ask whether and how strongly investment decisions of firms respond to stringency in environmental regulation. Environmental stringency is measured as (i)...

The paper develops a model of firm´s investment under uncertainty with financial market imperfections and analyzes the effects of financial constraints on firm´s investment. Firm´s investment is an increasing function of the firm´s marginal q, however the investment function is characterized...
