The Middle East was once seen as a medieval great globalized force. Nowadays it shows one of the lowest intra-regional trade in the world and therefore it is claimed that the region is poorly integrated. Yet, with the steady .ow of workers across national borders of the Middle East is this...

We have argued that from the standpoint of a policy maker, the uncertainty of using the average forecast is not the variance of the average, but rather the average of the variances of the individual forecasts that incorporate idiosyncratic risks. With a slight reformulation of the loss function...

This paper presents an empirical analysis of the relationship between fiscal illusion and the shadow economy for 104 countries over the period 1989-2009. We argue that both unobservable phenomena are closely linked to each other, as the creation of a fiscal illusion may be helpful if governments...

Unilateral climate policy induces carbon leakage through the relocation of emission-intensive and trade-exposed industries to regions with no or more lenient emission regulation. Both analytical and numerical studies suggest that emission pricing combined with border carbon adjustments may be a...

In this paper we argue that supply-side adjustments (i.e. the reallocation of productive resources between the traded and non-traded sectors) can be an important determinant of the output costs of current account adjustment. The argument relies on the fact that tax evasion is more prevalent in...

This paper examines how restrictions on the tax-deductibility of interest cost affect location choices of multinational corporations (MNCs). Many countries have introduced so-called thin-capitalization rules (TCRs) to prevent MNCs from shifting tax base to countries with lower tax rates. As of...

Global climate change and other environmental challenges require the development of new energy technologies with lower emissions. In the near-term, R&D investments, either by government or the private sector, can bring down the costs of these lower emission technologies. However, the results of...

This paper presents a dynamic model of risk-averse producers' decision to invest in physical capital and to export. The model features irreversible investment, no capital markets and fixed and sunk costs to export. Several features of the distribution of investment rates and export participation...

The conditional equity premium in the model with production is often approximated by assuming a jointly log-normal distribution of the marginal rate of substitution in consumption and the marginal productivity of capital. We show that, for standard parameterization, this premium is about one...

We derive a general optimal income tax formula when individuals respond along both the intensive and extensive margins and when income effects can prevail. Individuals are heterogeneous across two dimensions: their skill and their disutility of participation. Preferences over consumption and...
