French Polynesia exports more than 90 per cent of its pearl production, making it the world’s largest exporter of Tahitian black pearls. Tahitian black pearl exports are therefore crucial for the Tahitian economy as they accounted for an average of 50 per cent of total export earnings, for the latest data available, for the years 2004, 2005, and 2006. This means that export performance not only...

This paper uses a sample of 180,738 tax entities from the full Australian Tax Office (ATO) tax return data to investigate the determinants of profitability. The sample of Australian tax entities are averaged over the period 1994/95 to 1996/97. Analysis is carried out at a 3 digit ANZSIC level of classification. Using simple regression techniques the analysis suggests that size of entity is posi...

We investigate whether stock betas vary with the release of firm-specific news. Using daily firm-level betas estimated from intraday prices, we find that betas increase on earnings announcement days and revert to their average levels two to five days later. The increase in betas is greater for earnings announcements that have larger positive or negative surprises, convey more information about ...

We investigate the effects of human capital accumulation on trade and productivity by integrating a micro-founded education and fertility decision of households into a model of international trade with firm heterogeneity. Our theoretical framework leads to two testable implications: i) the export share of a country increases with the education level of its population, ii) the average profitabil...

Free entry equilibria are usually characterized by the zero profit condition. We plead instead for a strict application of the Nash equilibrium concept to a symmetric simultaneous game played by actual and potential entrants, producing under decreasing average cost. Equilibrium is then typically indeterminate, with a number of active firms varying between an upper bound imposed by profitability...

This paper seeks to investigate the determinants of banking network profitability in Iran from 2007 to 2012. The results of our study indicate that both bank-specific factors and macroeconomic factors influence banks’ profitability in Iran.

This study seeks to investigate the impact of the internal characteristics of banks, the structure of the banking industry and the economic situation of Iran on the profitability of the banking system of Iran by exploring the theory of the Structuralism school concerning...

We analyze optimal policy design when firms' research activity may lead to socially harmful innovations. Public intervention, affecting the expected profitability of innovation, may both thwart the incentives to undertake research (average deterrence) and guide the use to which innovation is put (marginal deterrence). We show that public intervention should become increasingly stringent as the ...

The global financial crisis had detrimental consequences for banks’ balance sheets, as well as for their funding costs and profitability, thus weighing negatively on their ability to supply new loans. As a result, banks tightened credit standards for all borrowers, including non-financial corporations. The restricted access to bank funding for the corporate sector induced the latter to seek oth...
