There has been increased interest in the use of "big data" when it comes to forecasting macroeconomic time series such as private consumption or unemployment. However, applications on forecasting GDP are rather rare. In this paper we incorporate Google search data into a Bridge Equation Model, a...

Virtually each seasonal adjustment software includes an ensemble of seasonality tests for assessing whether a given time series is in fact a candidate for seasonal adjustment. However, such tests are certain to produce either the same resultor conflicting results, raising the question if there...

Data revisions to national accounts pose a serious challenge to policy decision making. Well-behaved revisions should be unbiased, small and unpredictable. This paper shows that revisions to German national accounts are biased, large and predictable. Moreover, using filtering techniques designed...

We present a comprehensive disaggregate approach for short-term forecasting economic activity in Germany by explicitly taking into account the supply or production side and the demand side of GDP. The GDP figures calculated by the two sides usually yield different results and the official GDP...

This paper evaluates the economic effects of Turkish EU membership. The evaluation is based on a widely utilized computable general equilibrium model called GTAP (Global Trade Analysis Project). Imperfect competition is modelled via assumption of scale economies on non agricultural sectors. The...

In this paper we model foreign capital flow to Brazil as stemming from an investment decision that whose risk depends on the expected rate of loss of foreign reserves. This motivates the estimation of an empirical relationship between these two variables that is valid for "normal" periods (when...

This paper suggests a quantifiable multi-sector-multi-country economic model of goods and services production and consumption. It calibrates overall (variable and fixed) costs to market-specific sales by sector and decomposes these costs into observable and unobservable components. In an...

We analyze the effect of the increase in trade exposure induced by the rise of China and the transformation of Eastern Europe on collective bargaining coverage of German plants in the period 1996-2008. We exploit cross-industry variation in trade exposure and use trade flows of other high-income...
