  1. The textcat Package for n-Gram Based Text Categorization in R

    Feinerer, Ingo; Buchta, Christian; Geiger, Wilhelm; Rauch, Johannes; Mair, Patrick; Hornik, Kurt
    Identifying the language used will typically be the first step in most natural language processing tasks. Among the wide variety of language identification methods discussed in the literature, the ones employing the Cavnar and Trenkle (1994) approach to text categorization based on character n-gram frequencies have been particularly successful. This paper presents the R extension package textcat for n-gram based text categorization which implements both the Cavnar and Trenkle approach as well as a reduced n-gram approach designed to remove redundancies of the original approach. A multi-lingual corpus obtained from the Wikipedia pages available on a selection of topics is used to illustrate the functionality of the package...

  2. Does the Welfare State Destroy the Family? Evidence from OECD Member Countries

    Halla, Martin; Lackner, Mario; Scharler, Johann
    We study the effect of the size of the welfare state on family outcomes in OECD member countries. Exploiting exogenous variation in public social spending, due to varying degrees of political fractionalization (i.e. the number of relevant parties involved in the legislative process), we show that an expansion in the welfare state increases the fertility, marriage, and divorce rates with a quantitatively stronger effect on the marriage rate. We conclude that the welfare state supports family formation. Nevertheless, we also find that the welfare state decouples marriage and fertility, and therefore, alters the organization of the family.

  3. Does Custody Law Affect Family Behavior In and Out of Marriage?

    Böheim, Rene; Francesconi, Marco; Halla, Martin
    We examine the effect of joint custody on marriage, divorce, fertility and female employment in Austria using individual-level administrative data, covering the entire population. We also use unique data obtained from court records to analyze the effect on post-divorce outcomes. Our estimates show that joint custody significantly reduces divorce and female employment rates, significantly increases marriage and marital birth rates, and leads to a substantial increase in the total money transfer received by mothers after divorce. We interpret these results as evidence against Becker-Coase bargains and in support of a mechanism driven by a resource redistribution that favors men giving...

  4. The role of social expenditures in budget consolidations - an analysis of the fiscal and macroeconomic effects

    Gruber, Norbert
    This paper reviews and summarizes the literature that has concentrated on budget consolidations and their fiscal and economic effects. The issue of fiscal adjustments has again gained importance due to the recent economic crisis and the resulting fiscal imbalances. The existing literature shows that there may be some factors that influence the fiscal and economic impact depending on the methods used and the underlying assumptions. Referring to the fiscal impact of consolidations, this paper concludes that the composition of the adjustment is the most influential factor in reducing public deficits and debt. This result is in line with other recent literature surveys. Other factors mentioned in...
