The dynamism of air traffic markets in the Middle East obscures the persistence of restrictions on international competition. But how important are such restrictions for passenger traffic? This paper uses detailed data on worldwide passenger aviation to estimate the effect of air transport...

The paper presents the importance of the green economy for Romania in the context of sustainable development. It is known the critical state of environment, unsustainable exploitation of natural resources and population’s poverty. These phenomena are manifesting almost in all Europe that which...

There is significant debate over the effect of the Interstate Commerce Act (ICA) on the cost of rail transport to shippers. Taking price differences across locations as proxy for transport costs, we use data on wheat prices before and after the implementation of the ICA to see if the Act led to...

We collect extensive data on worldwide trade by transportation mode and use this to provide detailed comparisons of the greenhouse gas emissions associated with output versus international transportation of traded goods. International transport is responsible for 33 percent of world-wide...

Romania’s absorption capacity of EU structural and cohesion funds is based on the degree of implementation of Sectoral Operational Programmes (SOP) 2007-2013 within SOP Environment and plays a central role in view of its complex relationships (horizontal and vertical) with other SOPs.The...

This study uses cross-county variation in support for 46 ballot measures to identify political subcultures in South Dakota and to study them. A hierarchical clustering method applied to county-level election returns allows the identification of subcultures at various levels of granularity. We...

We present an empirical implementation of a general-equilibrium model of international trade with heterogeneous manufacturing firms. The theory underlying our model is consistent with Melitz (2003) and Bernard et al. (2004). A nonlinear structural estimation procedure identifies a set of core...

We present an empirical implementation of a general-equilibrium model of international trade with heterogeneous manufacturing firms. The theory underlying our model is consistent with Melitz (2003). A nonlinear structural estimation procedure identifies a set of core parameters and unobserved...
