  1. Timing Product Replacements under Uncertainty: The Importance of Material' Price Fluctuations for the Success of Products That Are Based on New Materials

    Fisch, Jan Hendrik; Ross, Jan-Michael
    Being first to market with new products is one of the most enduring pieces of strategic advice handed to managers. This view also emphasizes the importance of launching new products that are based on new materials as soon as possible. However, when the input costs of products that embody new materials are uncertain because of volatile material prices, the advantage of being an early mover comes along with the risk of paying unexpectedly high material prices. Real-option theory suggests delaying material substitution under uncertainty even if the new material enables superior product performance. Firms who have created the flexibility to switch between alternative inputs can...

  2. Aggregravity: Estimating Gravity Models from Aggregate Data

    Badinger, Harald; Crespo Cuaresma, Jesus
    This paper considers alternative methods to estimate econometric models based on bilateral data when only aggregate information on the dependent variable is available. Such methods can be used to obtain an indication of the sign and magnitude of bilateral model parameters and, more importantly, to decompose aggregate into bilateral data, which can then be used as proxy variables in further empirical analysis. We perform a Monte Carlo study and carry out a simple real world application using intra-EU trade and capital flows, showing that the methods considered work reasonably well and are worthwhile being considered in the absence of bilateral...

  3. Does Fiscal Consolidation Really Get You Down? Evidence from Suicide Mortality

    Antonakakis, Nikolaos; Collins, Alan
    While linkages between some macroeconomic phenomena (e.g. unemployment, GDP growth) and suicide rates in some countries have been explored, only one study, hitherto, has established a causal relationship between fiscal consolidation and suicide, albeit in a single country. This study examines the impact of budget consolidation on suicide mortality across all Eurozone peripheral economies, while controlling for various economic and sociodemographic differences. The impact of fiscal adjustments is found to be gender, age and time specific. In particular, fiscal consolidation has short-, medium- and long-run suicide increasing effects on the male population between 65 and 89 years of age. A...
