Towards an ecological understanding of firm founding and growth in emergent populations.

Organizational ecology is a fast growing domain in organization theory. During the past few years, the theory has evolved from a collection of rather unrelated concepts towards an integrated model of failure and founding, which has been tested with advanced empirical techniques. Despite this increasing convergence within the ecological boundaries, little integration occurs with other intellectual streams which can either be considered as complementary to a density dependence model or as a challenge to the basic assumptions of this model. This paper presents both a review of the theoretical and empirical methods developed during the past five years and an assessment of future research opportunities : can institutional theory, strategic management and industrial economics enrich and stretch the boundaries of the ecological model?

Does Information Technology Investment Influences Firm’s Market Value? The Case of Non-Publicly Traded Healthcare Firms

Managers make informed information technology investment decisions when they are able to quantify how IT contributes to firm performance. While financial accounting measures inform IT’s influence on retrospective firm performance, senior managers expect evidence of how IT influences prospective measures such as the firm’s market value. We examine the efficacy of IT’s influence on firm value combined with measures of financial performance for non-publicly traded (NPT) hospitals that lack conventional market-based measures. We gathered actual sale transactions for NPT hospitals in the United States to derive the q ratio, a measure of market value. Our findings indicate that the influence of IT investment on the firm is more pronounced and statistically significant on firm value than exclusively on the accounting performance measures. Specifically, we find that the impact of IT investment is not significant on return on assets (ROA) and operating income for the same set of hospitals. This research note contributes to research and practice by demonstrating that the overall impact of IT is better understood when accounting measures are complemented with the firm’s market value. Such market valuation is also critical in merger and acquisition decisions, an activity that is likely to accelerate in the healthcare industry. Our findings provide hospitals, as well as other NPT firms, with insights into the impact of IT investment and a pragmatic approach to demonstrating IT’s contribution to firm value

The impact of the maquiladora industry on U.S. border cities

For decades, the maquiladora industry has been a major economic engine along the U.S.–Mexico border. Since the 1970s, researchers have analyzed how the maquiladora industry affects cities along both sides of the border. Gordon Hanson (2001) produced the first comprehensive study on the impact of the maquiladoras on U.S. border cities, considering the impact of these in-bond plants on both employment and wages. His estimates became useful rules of thumb for the entire U.S.–Mexico border. These estimates have become dated, as Hanson's study covered the period from 1975 to 1997. The purpose of this paper is to update Hanson's results using data from 1990 to 2006 and to extend the estimates to specific border cities. For the border region as a whole, we find that the impact of a 10 percent increase in maquiladora production leads to a 0.5 to 0.9 percent change in employment. However, we also find that the border average is quite misleading, with large differences among individual border cities. Cities along the Texas–Mexico border benefit the most from growing maquiladora production. We also estimate the cross-border maquiladora impacts before and after 2001 when border security begins to rise, the maquiladora industry entered a severe recession and extensive restructuring and global low-wage competition intensified as China joined the World Trade Organization. Empirical results indicate that U.S. border cities are less responsive to growth in maquiladora production from 2001 to 2006 than in the earlier period; however, when looking into specific sectors we find that U.S. border city employment in service sectors are far more responsive post-2001.International trade ; Labor market ; Economic development - Latin America

Automation and Adaptation: Information Technology, Work Practices, and Labor Demand at Three Firms

The use of information and communication technology to automate routine tasks involves two types of innovation: technological and organizational. Together, improvements in technological capabilities and complementary changes made by firms in the way they organize work and implement work practices constitute the conditions under which machines substitute for or complement human workers. Building on the prevailing model of routine-biased technical change and recent insights into organizational complementarities, I conduct three qualitative case studies in health care and real estate to assess the relationship between technology and firm-level labor demand. Unique combinations of technological innovation, organizational complementarity, and decision-making at each firm produce differential impacts for labor demand, with even similar technologies exhibiting quite different patterns of substitution for workers of all skill types. In addition, studying firm-level complementarities illuminates how and why the scope of the routine task may be growing, with particularly important implications for relatively higher skill workers

Facility Location Planning in Relief Logistics: Decision Support for German Authorities

The delivery of essential goods to beneficiaries in the aftermath of a disaster is one of the main objectives of relief logistics. Thereby, the present work aims to improve relief logistics by improving the location selection of warehouses, distribution centers, and points of distribution. Consequently, it offers the potential to significantly improve the distribution of goods in the aftermath of future disasters and, thereby, increase disaster resilience

Bye, Bye, Miss American Pie? The Supply of New Recorded Music Since Napster

In the decade since Napster, file-sharing has undermined the protection that copyright affords recorded music, reducing recorded music sales. What matters for consumers, however, is not sellers’ revenue but the surplus they derive from new music. The legal monopoly created by copyright is justified by its encouragement of the creation of new works, but there is little evidence on this relationship. The file-sharing era can be viewed as a large-scale experiment allowing us to check whether events since Napster have stemmed the flow of new works. We assemble a novel dataset on the number of high quality works released annually, since 1960, derived from retrospective critical assessments of music such best-of-the-decade lists. This allows a comparison of the quantity of new albums since Napster to 1) its pre-Napster level, 2) pre-Napster trends, and 3) a possible control, the volume of new songs since the iTunes Music Store’s revitalization of the single. We find no evidence that changes since Napster have affected the quantity of new recorded music or artists coming to market. We reconcile stable quantities in the face of decreased demand with reduced costs of bringing works to market and a growing role of independent labels.

Facility Location Planning in Relief Logistics: Decision Support for German Authorities

Disasters have devastating impacts on societies, affecting millions of people and businesses each year. The delivery of essential goods to beneficiaries in the aftermath of a disaster is one of the main objectives of relief logistics. In this context, selecting suitable locations for three different types of essential facilities is central: warehouses, distribution centers, and points of distribution. The present dissertation aims to improve relief logistics by advancing the location selection process and its core components. Five studies published as companion articles address substantial aspects of relief logistics. Despite the case studies\u27 geographical focus on Germany, valuable insights for relief logistics are derived that could also be applied to other countries. Study A addresses the importance of public-private collaboration in disasters and highlights the significance of considering differences in resources, capabilities, and strategies when using logistical models. Moreover, power differences, information sharing, and partner selection also play an important role. Study B elaborates on the challenges to identify candidate locations for warehouses, which are jointly used by public and private actors, and suggests a methodology to approach the collaborative warehouse selection process. Study C investigates the distribution center selection process and highlights that including decision-makers\u27 preferences in the objective function of location selection models helps to raise awareness of the implications of location decisions and increases transparency for decision-makers and the general population. Study D analyzes the urban water supply in disasters using a combination of emergency wells and mobile water treatment systems. Selected locations of mobile systems change significantly if vulnerable parts of the population are prioritized. Study E highlights the importance of accurate information in disasters and introduces a framework that allows determining the value of accurate information and the planning error due to inaccurate information. In addition to the detailed results of the case studies, four general recommendations for authorities are derived: First, it is essential to collect information before the start of the disaster. Second, training exercises or role-playing simulations with companies will help to ensure that planned collaboration processes can be implemented in practice. Third, targeted adjustments to the German disaster management system can strengthen the country\u27s resilience. Fourth, initiating public debates on strategies to prioritize parts of the population might increase the acceptance of the related decision and the stockpiling of goods for the people who know in advance that they will likely not receive support. The present dissertation provides valuable insights into disaster relief. Therefore, it offers the potential to significantly improve the distribution of goods in the aftermath of future disasters and increase disaster resilience

Closed-World Semantics for Query Answering in Temporal Description Logics

Ontology-mediated query answering is a popular paradigm for enriching answers to user queries with background knowledge. For querying the absence of information, however, there exist only few ontology-based approaches. Moreover, these proposals conflate the closed-domain and closed-world assumption, and therefore are not suited to deal with the anonymous objects that are common in ontological reasoning. Many real-world applications, like processing electronic health records (EHRs), also contain a temporal dimension, and require efficient reasoning algorithms. Moreover, since medical data is not recorded on a regular basis, reasoners must deal with sparse data with potentially large temporal gaps. Our contribution consists of three main parts: Firstly, we introduce a new closed-world semantics for answering conjunctive queries with negation over ontologies formulated in the description logic ELH⊥, which is based on the minimal universal model. We propose a rewriting strategy for dealing with negated query atoms, which shows that query answering is possible in polynomial time in data complexity. Secondly, we introduce a new temporal variant of ELH⊥ that features a convexity operator. We extend this minimal-world semantics for answering metric temporal conjunctive queries with negation over the logic and obtain similar rewritability and complexity results. Thirdly, apart from the theoretical results, we evaluate minimal-world semantics in practice by selecting patients, based their EHRs, that match given criteria
