Representational Indeterminancy and Enterprise Search: The Importance of Subject Indexes

The proposed research examines the impact that adding context – via the use of subject indexes – to a query has on search results. This design science research is motivated by the need for a solution to the well-documented failure of enterprise search. Preliminary experimental data is presented that indicates that the use of subject indexes to augment full-text search may indeed be a valid solution and thereby encourages continued investigation. Continuing the research, we propose an experiment where we simulate the search for randomly selected (single) documents in a collection. We will use the comparison of search results between full-text only and full-text plus subject metadata searches to evaluate search performance. The primary dependent variable used will be the rank of the searched-for document in the result set returned by the search engine for each search

Earnings Inequality and the Global Division of Labor: Evidence from the Executive Labor Market

Many industrialized economies have seen a rapid rise in top income inequality and in the globalization of production since the 1980s. In this paper I propose an open economy model of executive pay to study how offshoring affects the pay level and incentives of top earners. The model introduces a simple principal-agent problem into a heterogeneous firm talent assignment model and endogenizes pay levels and the sensitivity of pay to performance in general equilibrium. Using unique data of manager-firm matches including executives from stock market listed firms across the U.S. and Europe, I quantify the model predictions empirically. Overall, I find that between 2000 and 2014 offshoring has increased executive pay levels, raised earnings inequality across executives and increased the sensitivity of pay to firm performance

Trade, Technologies, and the Evolution of Corporate Governance

Do international trade and technological change influence how firms create incentives for human capital? I present a model that incorporates agency problems into a framework with firm heterogeneity and human capital. My model indicates that trade liberalizations and skill-biased technological change alter the way how the largest firms in an economy incentivize their managers. Increases in managerial reservation wages lead to a reduction in corporate governance investments and a rise in performance compensation since monitoring managers becomes less efficient. Using data on CEO compensation and entrenchment opportunities in public industrial firms in the U.S., I document strong empirical regularities in support of the model predictions. Firms allow for more managerial entrenchment and offer larger CEO compensation when their industries become more open to trade or when production becomes more I.T. intensive

Europe's exports superstar - it's the organisation! Bruegel Working Paper 2015/05, 15 July 2015

What explains Germany’s superb export performance? Is Germany’s export behaviour very distinct compared to other European countries? The authors explore the organisational responses to competition of 14,000 exporting firms in seven European countries. The paper examines the export business model of the median exporter and of the top one percent exporters in each country, accounting for 20 percent to 55 percent of total exports. What do these firms do to become superstars? The authors find, first, that the export market share of the median exporter in each of the countries to the world more than tripled (in some cases the export market share increases tenfold) for firms that combine decentralised management with offshoring of production to low-wage countries. Exporters which abstain from any organisational adjustment do very badly. Decentralised management provides incentives for workers for product improvements allowing exporters to compete on quality. Offshoring production to low-wage countries reduces costs allowing exporters to compete on price. Second, we find that Germany is the leading quality exporter in Europe followed by Austria and Spain. Among the top 10 percent of exporters there is no single firm with low quality in Germany and Austria, which suggest that decentralised management has provided incentives for quality in these countries. Third, Germany’s exports are less vulnerable to price increases, while exports from France and Italy respond strongly to price changes, and thus costs reductions via offshoring benefits these countries most

Managing Government Regulatory Requirements for Security and Privacy Using Existing Standard Models

This paper posits the use of a well-established standard approach to Federal compliance, which can be easily adapted to satisfy all legal and regulatory requirements for protection of patient personally identifiable information (PII) in health organizations. This approach is embodied in the three standards that dictate how to comply with the Federal Information Security Management Act (FISMA). These standards also provide an excellent foundation for organizing a secure operation anywhere. The discussion revolves around the application of the FIPS 199 and FIPS 200/NIST 800-53(4) standard approach to the satisfaction of the present and upcoming legal and regulatory requirements for health care PII. The outcome would provide a proven, systematically secure and cost efficient solution to those protection needs. The general approach will be explained and justified

Import Competition and the Composition of Firm Investments

We study how foreign competition affects the composition of investments inside firms. A parsimonious model predicts that firms have an incentive to shift their investments towards more short-term assets when exposed to tougher competition. Using data on expenditures of listed US companies into various asset classes with different lifespans, we document empirical evidence that is consistent with this prediction. Over a fifteen year period between 1995 and 2009, the rise in import competition is associated with a reduction of the firm-specific asset lifespan by about 4.5% on average. We additionally exploit the Chinese WTO accession as an exogenous shock in firm expectations about future exposure to competition
