Planning in Turbulent Times: Exploring Planners' Agency in Jerusalem

This article explores the role of planning in the deeply divided and politically polarized context of Jerusalem. The overall argument developed throughout the article is that the relation between planning and politics is a non‐hierarchical set of interactions, negotiated within specific historical, geographical, legal and cultural contexts—in other words, orders don't come down from the politicians to be slavishly followed by planners. In this respect our findings, based on in‐depth interviews with Israeli planners, suggest that the case of Jerusalem represents a particularly dramatic illustration of the fact that the function of planning expertise can only be understood in relation to the surrounding socio‐political environment. Furthermore, contrary to conventional wisdom, planners in Jerusalem are not destined to either complicity or irrelevance in the face of political imperatives; planners' agency, however, does not simply reflect their mastery of specific professional knowledge and tools, but also their ability to act strategically in relation to the context in which they operate.     

THE EFFECT OF PARENTAL EMPLOYMENT ON CHILD SCHOOLING

This paper presents a model that provides conditions under which a causal interpretation can be given to the association between childhood parental employment and subsequent educational attainments of children. The key parameter comes from theconditional demand function for children's future earning capacity. Its identification rests on having data on siblings and assumptions about the timing of parents' knowledge of their children's endowments. In addition to sibling differences, the useof a fixed‐effects instrumental‐variables estimator identifies the parameter under weaker conditions. Empirical analysis informed by the model reveals a negative and significant effect on the child's educational attainment of the months of the mother's full‐time employment when the child was aged 0–5. The effect of the mother's part‐time employment is smaller and less well determined, but again negative. These results suggest that the substitution effect of the mother's employment dominates the income effects. Stronger adverse effects are found for children of less‐educated mothers.

Network formation models with costs for establishing links

Abstract. In this paper we study endogenous formation of communication networks in situations where the economic possibilities of groups of players can be described by a cooperative game. We concentrate on the influence that the existence of costs for establishing communication links has on the communication networks that are formed. The starting points in this paper are two game-theoretic models of the formation of communication links that were studied in the literature fairly recently, the extensive-form model by Aumann and Myerson (1988) and the strategic-form model that was studied by Dutta et al. (1998). We follow their analyses as closely as possible and use an extension of the Myerson value to determine the payoffs to the players in communication situations when forming links is not costless. We find that it is possible that as the costs of establishing links increase, more links are formed.     

Shaping buyer–supplier relationships in manufacturing contexts: Design and test of a contingency model

Although the idea that buyer–supplier partnerships can yield considerable benefits to firms is largely diffused among researchers and practitioners, the approach adopted in this paper is that no “one best way” exists in buyer–supplier relationships, but rather a “best way” for each specific exchange context. Hence, this paper proposes a contingency model for shaping and managing buyer–supplier relationships in manufacturing contexts. In order to test the model, an empirical study was performed on a sample of 45 buyer–supplier relationships within the Italian white goods industry. A three-dimensional performance indicator was computed to compare supplier performance achieved within relations matching the model's suggestions with those set differently. The results strongly suggest that suppliers involved in relationships set accordingly to the contingency model are likely to enjoy superior performance.     

The Effects of Auditor Social and Human Capital on Auditor Compensation: Evidence from the Italian Small Audit Firm Market

Abstract

This study examines whether social and human capital influence the compensation of individual auditors in the small audit firm market. We employ a sample of Italian auditors and use measures from the network and auditing literatures to capture their professional connections, representing social capital, and their industry expertise, representing human capital. Our findings show a positive and economically meaningful association between these individual attributes and auditor compensation. We run several tests to address potential endogeneity issues in our research design. Our results suggest that, in the small audit market, clients perceive as valuable those auditors with higher social and human capital, and as a result, are willing to pay a premium for these specific auditor attributes.     

The emergence of new networked business models from technology innovation: an analysis of 3-D printing design enterprises

Technology does not have intrinsic value: obtaining competitive advantage from it and transforming it into profits requires a business model based on the application of competencies and dynamic capabilities, and the ability to select and apply appropriate resources. Innovative 3-D printing technology appears to be dependent on a new business model based on the ability to structure and integrate creative inputs, crowdsourcing processes, and market distribution networks. This new business model is being used by design enterprises that employ 3-D printing technology in order to enrich their service portfolio or to inaugurate completely new business lines. This paper analyzes how the use of new 3-D printing technology in design enterprises is coupled with proper business model components. Through a qualitative analysis of three cases - Quirky, i.materialise and Fab-Lab - the authors develop four propositions on a number of factors that contribute to business model effectiveness in design ventures using 3-D printing technology.     

Financial dollarization and systemic risks: New empirical evidence

This paper explores the persistence of financial dollarization in a group of 79 economies with different levels of development. Our main hypothesis is that a high level of domestic debt combined with default risk explains this persistence, even after a decline in inflation rates. Using the generalized method of moments (GMM) in a panel data analysis, our results show that inflation risks caused by increasing probability of default account for financial dollarization more than inflation rate itself. After the decrease in inflation rates, the foreign currency-denominated deposits remain large because of the high debt-to-GDP ratios, particularly in speculative-grade economies. High public indebtedness leads to expectations of default. Dollarization is a rational response to the future inflation associated with investors' expectations of default observed in highly indebted economies.     

Optimal strategy for a fund manager with option compensation

I consider the problem of portfolio optimization for a manager whose compensation is given by the sum of a constant and a variable term. The constant term is a fixed percentage of the managed funds that is payed to the manager independently of his performance. The variable term is a premium that is proportional to the profit earned by the manager over a benchmark at a certain evaluation date. I find the optimal strategy and the optimal portfolio value in the Black–Scholes setting when the benchmark is a linear combination of the risky asset and the money market account.     

The Impact of an increasing share of RES-E on the Conventional Power Market — The Example of Germany

The intermittency of wind power has a decreasing effect on day-ahead spot prices. Data from Germany illustrate this effect and explain the underlying relationships. This short-term price effect leads to an adaptation process in the conventional generation capacity mix. In the long-run, a higher peak load plant share is required to cope with the increasing volatility of the residual demand. The result is an adapted merit-order. This merit-order intersects with an increasingly volatile residual demand curve and leads to a higher price volatility in the power market, which is going to trigger further adaptations. Therefore this article concludes with a list of open research questions, which can be derived from the illustrated relationship. These research questions should be investigated as soon as possible in order to induce the required adaptations in time.     

Firm Size and Growth Rate Variance: The Effects of Data Truncation

This paper discusses the effects of the existence of natural and/or exogenously imposed thresholds in firm size distributions on estimations of the relation between firm size and the variance in firm growth rates. We argue that these estimations are upwardly biased whenever the threshold operates on the same proxy that is used to calculate the growth rates. We show the potential impact of the bias on simulated data, suggest a methodology to improve these estimations, and present an empirical analysis on Dutch firms. The only stable relation that emerges is the negative relationship between firm size and growth rate variance.
