  • Mueller, Andreas, 1979- (författare)
  • Business Cycles, Unemployment and Job Search : Essays in Macroeconomics and Labor Economics
  • 2011
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • This thesis consists of four essays. The first essay, "Separations, Sorting and Cyclical Unemployment", establishes a new fact about the compositional changes in the pool of unemployed over the U.S. business cycle and evaluates a number of theories that can potentially explain it. Using longitudinal micro-data from the Current Population Survey 1979-2008, it documents that in recessions the pool of unemployed shifts towards workers with high wages in their previous job. The essay also shows that a search-matching model with endogenous separations and worker heterogeneity in terms of ability has difficulty in explaining these patterns, but an extension of the model with credit-constraint shocks does much better in accounting for the new fact. The second essay, "The Lot of the Unemployed: A Time Use Perspective", provides new evidence on the time use of employed and unemployed individuals in 14 countries. It devotes particular attention to characterizing and modeling job search intensity, measured by the amount of time devoted to searching for a new job. Job search intensity varies considerably across countries, and is higher in countries that have higher wage dispersion. The third essay, "Job Search and Unemployment Insurance: New Evidence from Time Use Data", examines the relationship between Unemployment Insurance and job search intensity. Among the major findings are that, across the U.S. states, job search is inversely related to the generosity of unemployment benefits and that job search intensity for those eligible for Unemployment Insurance increases prior to benefit exhaustion. The fourth essay, "On-the-Job Search and Wage Dispersion: New Evidence from Time Use Data", finds that on-the-job search effort, modeled as time allocated to job search activities, is decreasing in the wage of the current job. The evidence presented is consistent with models where similar workers face wage dispersion and invest time in order to find better paying jobs.

  • Reconsidering the Geographical Flows of the Global Knowledge Economy : The Example of Indian ICT-Based Knowledge Flows to Sweden
  • 2011
  • Ingår i: International Journal for Digital Society (IJDS). - 2040-2570. ; 2:2, s. 451-461
  • Tidskriftsartikel (refereegranskat)abstract
    • This article discusses the geographical flows of the global knowledge economy and their unstable and rapidly changing nature. We use the development of activities in ICT (information and communication technology) in India and its connections to Sweden to illustrate changes in international business. The article explores the ways in which transformations in geography and spatial relations, politics and management are causes and effects of rapid and profound transformations in the global economy. The transformations we illustrate provide reasons to reconsider the conventional idea of uneven power relations in the world, between the stronger “global North” and the weaker “global South”. Firms based in the global South and in India develop their organizations and capabilities to compete for market share worldwide, and on the same basis as firms based in the global North.

  • Managing Healthy Organizations : worksite health promotion and the new self-management paradigm
  • 2011
  • Bok (övrigt vetenskapligt/konstnärligt)abstract
    • The corporate management has come to take an active role in health promotion programming for employees, offering health education, screenings, therapy, and even leisure initiatives. This title argues that this narrow focus, and the typical uncritical standpoint towards initiatives which are taken in the name of employees' health, is inadequate.

  • Essays on Empirical Macroeconomics
  • 2011
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • This thesis consists of four essays in empirical macroeconomics. What Are the Effects of Fiscal Policy Shocks? A VAR-Based Comparative Analysis The literature using structural vector autoregressions (SVARs) to assess the effects of fiscal policy shocks strongly disagrees on the qualitative and quantitative response of key macroeconomic variables. We find that controlling for differences in specification of the reduced-form model, all identification approaches used in the literature yield similar results regarding the effects of government spending shocks, but diverging results regarding the effects of tax shocks. The Analytics of SVARs. A Unified Framework to Measure Fiscal Multipliers Does fiscal policy stimulate output? SVARs have been used to address this question, but no stylized facts have emerged. I show that different priors about the output elasticities of tax revenue and government expenditures implied by the identification schemes generate a large dispersion in the estimates of tax and spending multipliers. I estimate fiscal multipliers consistent with prior distributions of the elasticities computed by a variety of empirical strategies. I document that in the U.S. spending multipliers are larger than the tax multipliers. Computing DSGE Models with Recursive Preferences and Stochastic Volatility This paper compares solution methods for computing the equilibrium of dynamic stochastic general equilibrium models with recursive preferences and stochastic volatility. The main finding is that a third-order perturbation is competitive in terms of accuracy with Chebyshev polynomials and value function iteration, while being an order of magnitude faster to run. Business Cycle Accounting and Misspecified DSGE Models This paper investigates how insights from the literature on business cycle accounting can be used to trace out the implications of missing channels in a baseline estimated dynamic stochastic general equilibrium model used for forecast and policy analysis.

  • The Reproduction of Efficiecy Theory : The Construction of the AstraZeneca Merger in the Public Discourse
  • 2011
  • Ingår i: International Journal of Business and Management. - : Canadian Center of Science and Education. - 1833-3850 .- 1833-8119. ; 6:5, s. 16-27
  • Tidskriftsartikel (refereegranskat)abstract
    • Mergers have become a generally accepted solution to a broad set of managerial problems in practice. However, research on mergers and acquisitions provides a rather sceptical view as to the success of mergers in solving business problems. The current paper aims at investigating the public discourse on mergers and acquisitions and its relation to the scientific discourse. The public discourse is studied by an analysis of Swedish media reports on the Astra Zeneca merger. More specifically we study the actors given voice in the discourse, the temporal evolution of the discourse and the arguments voiced. We conclude that the discourse is dominated by journalists, managers and financial analysts who all generate arguments based on a rather narrow “efficiency theoretical” basis. This is in conflict with current insights in research on mergers and acquisitions that has proposed more valid and complex models for understanding mergers. The reasons and consequences of this discrepancy between the public and the scientific discourses are discussed.

  • Exploring public IT procurement : Switching Costs in the wake of a turn-to-services
  • 2011
  • Ingår i: Proceedings of 8th Scandinavian Workshop on E-government.
  • Konferensbidrag (refereegranskat)abstract
    • Technological and business-model related developments have continued to push the view that services and not software packages are the upcoming commodities within IT. This can be seen in the wide-spread adoption of Service Oriented Architecture (SOA) as the de-facto standard for new systems, and the radical increase in Software as a Service and other Cloud Computing based technologies as the business-models of choice for IT procurement. This” turn-to-services” brings with it promises of a better fit between IT supply and the changing demands of customers, and an increased competition between interoperable services in the market. Public Sector IT Procurement (PSITP) has yet to see mainstream adoption of these new business-models, yet the promises of reduced price and increased fit are still there. This paper builds on the assumptions that high switching cost is a factor that reduces the competition on the market for PSITP (Porter, 1980; Frendell, 1995). The paper presents a design science (Peffers et al, 2007) approach towards studying PSITP switching costs. A model for estimating switching cost is developed and a roadmap for demonstrating and evaluating the model is presented.

  • Studying the Implications of Cloud-based delivery models on public IT procurement: A switching cost perspective
  • 2011
  • Ingår i: eChallenges e2011, Florence, Italy. - 9781905824274
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • Public sector IT procurement has received limited interest from the research community, despite the vastness and importance of the phenomena. Following contemporary developments in a “turn-to-services”, with more and more of the total IT environment being supplied through cloud-based delivery models, this paper explores the potential in using switching costs as an approach for studying public sector IT procurement. Through presenting and contrasting two theoretical models for switching cost estimation, this paper discusses the use of switching costs as a perspective in the study of public sector IT procurement of cloud-based services. As the results show, switching costs is a valuable way ahead, and the paper lists some design implications for research into the field.

  • The Causal Effect of Parents' Schooling on Children's Schooling : A Comparison of Estimation Methods
  • 2011
  • Ingår i: Journal of Economic Literature. - : American Economic Association. - 0022-0515 .- 0364-281X. ; 49:3, s. 615-651
  • Tidskriftsartikel (refereegranskat)abstract
    • We review the empirical literature that estimates the causal effect of parent’s schooling on child’s schooling, and conclude that estimates differ across studies. We then consider three explanations for why this is: (a) idiosyncratic differences in data sets, (b) differences in remaining biases between different identification strategies, and (c) differences across identification strategies in their ability to make out-of-sample predictions. We conclude that discrepancies in past studies can be explained by violations of identifying assumptions. Our reading of past evidence, together with an application to Swedish register data, suggests that intergenerational schooling associations are largely driven by selection. Parental schooling constitutes a large part of the parental nurture effect, but as a whole does not play a large role.
