We study the sensitivity of investment to cash flow conditional on measures of q in an adjustment costs framework with costly external finance. We present a benchmark model in which this conditional investment-cash flow sensitivity increases monotonically with the cost premium for external...

Abel and Eberly (1999) prove that uncertainty has an ambiguous effect on long run capital accumulation in a real options model. We show that, with adjustment costs quadratic in investment, more uncertainty reduces capital and this effect may be large.

We study the sensitivity of investment to cash flow conditional on measures of q in an adjustment costs framework with costly external finance. We present a benchmark model in which this conditional investment–cash flow sensitivity increases monotonically with the cost premium for external...

This paper tests for the importance of cash flow on investment in fixed capital and R&D using firm-level panel data in two countries between 1985 and 1994. For German firms, cash flow is not informative in simple econometric models of fixed investment or R&D. In identical specifications for...

This paper uses Monte Carlo simulations to investigate the impact of nonstationarity, parameter heterogeneity and cross-section dependence on estimation and inference in macro panel data. We compare the performance of standard panel estimators with that of our own two-step method (the AMG) and...

Recent reforms in most African economies of their trading and exchange rate regimes have eliminated much of the protection which previously limited competition. Despite these reforms, African manufacturing firms remain unsuccessful, particularly in international export markets. In this paper we...

Using matched employer-employee data on 10 African countries, this paper examines the relationship beween wages, worker supervision, and labor productivity in manufacturing. Wages increase with firm size for both production workers and supervisors. We develop a two-tier model of supervision that...

This paper considers the relationship between two general neutral business tax structures, which we label the ‘firm tax’ and the ‘shareholder tax’. The well-known R-based and S-based cash flow taxes, analysed by Meade (1978), are special cases of these two taxes. We demonstrate the...
