Firms in tradable sectors are more likely to be subject external competition limit market power, while nontradable firms dependent on domestic policies and institutions. This paper combines an antitrust index available for multiple countries with firm-level data from Orbis covering than 12 million 94 countries, including 20 over 10 years finds that profit margins of operating significantly lowe...

Legal simplification may improve the quality of institutions in industrialised countries that developed over-complex legal systems. In theory, this type of regulatory reform promotes economic efficiency, leading to higher levels of productivity and output. In this paper we use a Panel Factor-Augmented VAR approach to measure the long-run impact of legal-simplification programmes in total factor...

Labor and product market regulations affect the unemployment rate of a country without doubt. Econometricians, however, have yet to establish an unequivocal significance of this impact. Model mis-specification, one of the main underlying problems, is overcome by adopting a Bayesian Model Averaging approach. I apply this method to a panel data set that covers 17 OECD countries for the time perio...

Isolated effects of labor and product market institutions as well as the interaction between both aforementioned categories on unemployment have been extensively discussed in the empirical literature. However, interaction effects between individual labor market institutions have been widely neglected, mainly due to the infeasibility to correctly specify the model. In this paper, a model averagi...

This study investigates the impact of certain macroeconomic determinants on stock market returns in Gulf Cooperation Council (GCC). Those factors are: interest rates, oil prices, exchange and money supply. were empirically studied investigated to have an many countries. paper also attempts capture that those market, using a panel set data by implying several tests data, which include unit root ...

The average time delay of photons due to multiple interactions with gravitons of the background is computed in a frame of the model of low-energy quantum gravity by the author. The two variants of evaluation of the lifetime of a virtual photon are considered: 1) on a basis of the uncertainties relation (it is a common place in physics of particles) and 2) using a conjecture about constancy of t...

The exchange rate plays an essential role for firms which export goods and import raw materials. In this paper, the effects of real specific exchange rate fluctuations in imports, exports and aggregate trade on industry sector, chemical and transportation industries outputs in 49 OIC countries were investigated by using a panel data model over 1990-2014. Particularly, this paper presents eviden...

This paper investigates several key challenges faced by oil-rich countries regarding their economic growth and development. First, it discusses how to determine currency overvaluation for these (if any). To the overvaluation, real exchange rate (RER) is calculated Balassa–Samuelson effect estimated via a regression model. Next, study presents an empirical model assessing impact of oil rent on i...
