EventKG: A Multilingual Event-Centric Temporal Knowledge Graph

One of the key requirements to facilitate semantic analytics of information regarding contemporary and historical events on the Web, in the news and in social media is the availability of reference knowledge repositories containing comprehensive representations of events and temporal relations. Existing knowledge graphs, with popular examples including DBpedia, YAGO and Wikidata, focus mostly on entity-centric information and are insufficient in terms of their coverage and completeness with respect to events and temporal relations. EventKG presented in this paper is a multilingual event-centric temporal knowledge graph that addresses this gap. EventKG incorporates over 690 thousand contemporary and historical events and over 2.3 million temporal relations extracted from several large-scale knowledge graphs and semi-structured sources and makes them available through a canonical representation

Firm Heterogeneity and Firm Behavior with Conditional Policies

This paper shows that the result of Ju and Krishna (2002, 2005), i.e., the non-monotonicity in the comparative statics across regimes, disappears, if exporters differ in their productivities, which provides very different predictions about the results of policy changes.

Trade and Trade Policy with Differentiated Products: A Chamberlinian-Ricardian Model: A Comment

This paper shows that the results of Venables (1987) depend critically on the assumption that there are no fixed costs of trade. The introduction of fixed costs of exporting, while making the model more consistent with the empirical evidence, leads to the opposite conclusion that technological progress in one country cannot harm the welfare of its trading partner. However, the results can be obtained in a richer setting with heterogeneous firms.

The Impact of Crises on Youth Unemployment of Russian Regions: An Empirical Analysis

The main purpose of this paper is to estimate the influence of the 1998 and 2008 crises on the youth unemployment rates (age class 20-29) in Russian regions. The investigation is founded on the panel data for 78 Russian regions during 1997–2008 provided by ROSSTAT (the main Russian State statistical organization). We compare the level and dynamics of the youth unemployment in various Russian regions and try to solve three main questions. Are there any special features of the youth unemployment in comparison with overall unemployment? How the 1998 crisis did change - and how the 2008 crisis is going to change - the youth unemployment dynamics? What can we learn from the impact of 1998 crisis and what is the main difference with the impact of the 2008 crisis? With the help of the obtained results we define some preliminary policy suggestion.financial crises, regional youth unemployment, Russian labour market.

Gold in the investment portfolio

The paper examines the key drivers of gold investment. Since 2000 the gold price has risen drastically, making gold an interesting add-on to a portfolio. As gold futures have negative roll returns, gold pool accounts are characterized by high credit risk and physical possession of gold means high transaction costs, Xetra-Gold might be the most efficient way to enter the market. Xetra-Gold is a product created by the Deutsche Börse in 2007, which is handled like a security but can be exchanged into physical gold any time. In the portfolio context gold has had a positive impact on Euro and USD portfolios between 2000 and 2006 due to considerable returns and low correlation to other assets. However, this has not been true for almost all other periods, the correlation was always low but the returns of gold were almost zero, overriding the positive diversification effect. --Investing in gold,gold in the portfolio,correlation of gold,returns of gold,Xetra-Gold
