Over the last decade many developing countries strengthened their transparency standards with the objective of improving asset market allocations and macroeconomic outcomes. This paper develops a general equilibrium model and argues that in a financially underdeveloped economy - with uninsurable consumption risk and stochastic-investment - enforcing financial transparency might be counterproductive. The framework builds upon a standard property that illiquid asset markets cause under-investment in assets that pay in the long-run, because individually rational agents hoard cash to exploit sales of underpriced long-term assets. First, I show that in this environment private revelation of news about investment-returns could give a chance to sell low-quality assets and then characterize the conditions under which the lack of financial transparency reduces under-investment and improves macroeconomic development. An empirical analysis reveals that the theoretical predictions of the model is in line with cross-country data.
