TAX POLICY AND INCOME INEQUALITY IN THE UNITED STATES, 1979–2007

This paper assesses the effects of U.S. tax policy reforms on inequality over around three decades, from 1979 to 2007. It applies a new method for decomposing changes in government redistribution into (1) a direct policy effect resulting from policy changes and (2) the effects of changing market incomes. Over the period as a whole, the tax policy changes increased income inequality by pushing up the income share of high‐income earners (the top 20%). (JEL H23, H31, H53, P16)     

The Business Model Paradox: A Systematic Review and Exploration of Antecedents

The business model has become a popular concept in business and management fields. Yet, it is suffering from a paradox between outstanding popularity and severe criticism, which appears to impede the positive development of the scholarly discourse on the business model concept. Against this background, the purpose of this study is to provide insight into the antecedents of this paradox and to understand their implications for the future development of the concept. The following contributions are made. First, the authors apply a narrative approach to recognizing and interpreting the paradox, and introduce the analysis of syntactics of scholarly discourse as a novel method of investigating management concepts. Second, as a result of elaborating on recurrent themes and tensions in scholarly discourse, the authors extend the literature on business models through theorizing on the core of the concept along the dimensions of classification, constitution and configuration. In particular, they identify the simultaneity of separation and attachment as the main antecedent of the business model paradox. Third, the authors offer implications for further advancing the development of this management concept, and highlight the need for spurring integrative research while at the same time maintaining a plurality of perspectives.     

Fertility and union formation during crisis and societal consolidation in the Western Balkans

Fertility decline in central and eastern Europe (CEE) since the fall of the communist regimes has been driven by both stopping and postponement of childbearing: two processes that have been related to crisis and economic development, respectively. In the Western Balkans these economic and political contexts followed each other in the form of a biphasic transition. I examine whether this sequence triggered fertility responses like those observed elsewhere. Relying on three independent data sources, I cross-validate the levels of, and describe the trends in, union formation and fertility (by birth order) between 1980 and 2010. Results do not reveal widespread declines in fertility to lowest-low levels during the most acute period of crisis. The subsequent postponement of marriage and first birth was also limited, and the two-child family remains the norm. This relative resilience of childbearing patterns compared with other CEE countries is discussed with reference to the institutional context.     

Estimation of causal effects in observational studies with interference between units

Causal effects are usually estimated under the assumption of no interference between individuals. This assumption means that the potential outcomes for one individual are unaffected by the treatments received by other individuals. In many situations, this is not reasonable to assume. Moreover, not taking interference into account could result in misleading conclusions about the effect of a treatment. For two-stage observational studies, where treatment assigment is randomized in the first stage but not in the second stage, we propose IPW estimators of direct and indirect causal effects as defined by Hudgens and Halloran (J Am Stat Assoc 103(482):832–842, 2008) for two-stage randomized studies. We illustrate the use of these estimators in an evaluation study of an implementation of Triple P (a parenting support program) within preschools in Uppsala, Sweden.     

Immigration and status exchange in Australia and the United States

This paper evaluates the status exchange hypothesis for Australia and the United States, two Anglophone nations with long immigration traditions whose admission regimes place different emphases on skills. Using log-linear methods, we demonstrate that foreign-born spouses trade educational credentials via marriage with natives in both Australian and U.S. marriage markets and, moreover, that nativity is a more salient marriage barrier for men than for women. With some exceptions, immigrant spouses in mixed nativity couples are better educated than native spouses in same nativity couples, but status exchange is more prevalent among the less-educated spouses in both countries. Support for the status exchange hypothesis is somewhat weaker in Australia partly because of lower average levels of education compared with the United States and partly because of the less sharply defined educational hierarchy at the postsecondary level.     

Fertility Decline During Albania’s Societal Crisis and its Subsequent Consolidation

Cross-sectional comparisons of the decline in fertility in former socialist countries point to a bi-phasic response: a crisis-induced family limitation followed by the postponement of childbearing during economic and political consolidation. In this article, the last two decades of Albania’s fertility transition are documented. The bi-phasic response model is tested in a period analysis of adaptations in marriage and parity-specific fertility to the socio-economic and political transformations since the fall of communist rule. We find that the timing and patterns of changes in Albanian family behaviours generally adhere to the model. Socio-economic differentials and trends are congruent with the major role played by the crisis and structural change. However, the Albanian case also highlights the enduring importance of traditional family formation models during the crisis, as well as among specific subpopulations more recently. These results are discussed with reference to a sociological account of Albanian society.     

Einf��hrung von Kommunikationsstandards in Unternehmensnetzwerken �C ein gestaltungsorientierter Ansatz bei dezentraler Entscheidungsstruktur

Standards and technologies (e.g. in the area of web services) that are currently discussed in research and practice will strongly change IT-based communication between organizations. However, the decision to standardize is accompanied by the risk of introducing a standard that is not adopted by other organizations afterwards. Hence, the interdependencies among the standardization decisions due to positive network effects result in a coordination problem, which is referred to as ??the standardization problem??. If the standardization decisions are taken by autonomous actors (e.g. legally independent organizations) that do not know the standardization decisions of the other actors in the network, this standardization problem arises for a decentralized decision structure and incomplete information. Thus, actors have to decide under uncertainty on whether to standardize or not. To avoid resulting inefficiencies and wrong decisions, we propose a formal, normative approach. This approach allows an actor within the network to anticipate the standardization decisions of the other actors and the associated network effects. Central to our approach are the consideration of interdependencies among the standardization decisions and the solution of the resulting system of equations.     

FROM FLEXIBILITY TO INSECURITY: HOW VERTICAL SEPARATION AMPLIFIES FIRM‐LEVEL UNCERTAINTY

This article presents a model where firms may endogenously externalize part of their production process. We start from the premise that adaptation to uncertainty cannot be contracted upon in the worker/employer relationship. Vertical separation then balances flexibility gains against hold‐up costs of opportunistic behavior by outside contractors. In equilibrium, the degree of separation is shown to depend on the degree of product market competition, contractor's bargaining power, and the volatility of demand shocks. Our main result is that an increase in the degree of vertical separation amplifies the elasticity to demand shocks of firms' sales and employment. It does not, however, amplify aggregate uncertainty. Evidence from firm‐level data is shown to be largely consistent with the main implications of our theory. (JEL: L16, L23, L24)
