Negotiators’ Attitudes toward Signing Business Contracts: Evidence from Greece and Israel

This study extends beyond negotiation process and styles, and focuses on negotiators’ tendency to sign formal contracts. Drawing on a risk mitigation perspective, it examines the influence of businesspeople's levels of horizontal and vertical individualism‐collectivism, ethical idealism, and trust propensity on their attitudes toward signing formal negotiated business contracts in Greece and in Israel. A survey questionnaire was translated from English to Greek and to Hebrew, and 649 responses were collected from employees who worked in industries such as banking, insurance, construction, manufacturing, retailing, and tourism in the Greek and Israeli private and public sectors. Our findings suggest that higher levels of horizontal individualism, horizontal collectivism, and ethical idealism increase employees’ tendency to sign formal contracts, whereas lower levels of general trust are associated with a higher propensity to sign formal contracts. Interestingly, employees’ propensity to sign formal contracts was significantly lower in Israel than in Greece. We argue that the propensity to sign formal contracts, and thus to mitigate potential agreement risks, is dependent on the individuals’ cultural and personal attributes. The study provides practitioners with a set of cultural and individual attributes that can serve as predictors of negotiators’ predisposition toward signing business contracts. © 2015 Wiley Periodicals, Inc.     

The economic impact of subsidized industrial R&D in Israel

Israel offers contingent subsidies to selected industrial R&D projects, with the purpose of creating high–quality jobs, reducing the trade deficit, increasing productivity and promoting growth. In 1987–94, 1,200 firms received $1,400 million of subsidies in support of $3,500 million of R&D (in constant 1996 dollars). We estimate that this R&D generated more than $31,000 million of sales, increasing industrial employment by about 10% and contributing to the trade balance a sum slightly less than the entire private sector deficit in the current account. It added 0.3% to GDP in increased productivity, each dollar of supported R&D adding an additional $0.45 to GDP and earning the economy a direct annual return of 13.4%. Electronics, broadly defined, received roughly half the subsidies while accounting for nearly two thirds of the gains; small firms that received one sixth of the subsidies contributed over a quarter of the gains.     

ASSET ALLOCATION AND ANNUITY-PURCHASE STRATEGIES TO MINIMIZE THE PROBABILITY OF FINANCIAL RUIN

In this paper, we derive the optimal investment and annuitization strategies for a retiree whose objective is to minimize the probability of lifetime ruin, namely the probability that a fixed consumption strategy will lead to zero wealth while the individual is still alive. Recent papers in the insurance economics literature have examined utility-maximizing annuitization strategies. Others in the probability, finance, and risk management literature have derived shortfall-minimizing investment and hedging strategies given a limited amount of initial capital. This paper brings the two strands of research together. Our model pre-supposes a retiree who does not currently have sufficient wealth to purchase a life annuity that will yield her exogenously desired fixed consumption level. She seeks the asset allocation and annuitization strategy that will minimize the probability of lifetime ruin. We demonstrate that because of the binary nature of the investor's goal, she will not annuitize any of her wealth until she can fully cover her desired consumption with a life annuity. We derive a variational inequality that governs the ruin probability and the optimal strategies, and we demonstrate that the problem can be recast as a related optimal stopping problem which yields a free-boundary problem that is more tractable. We numerically calculate the ruin probability and optimal strategies and examine how they change as we vary the mortality assumption and parameters of the financial model. Moreover, for the special case of exponential future lifetime, we solve the (dual) problem explicitly. As a byproduct of our calculations, we are able to quantify the reduction in lifetime ruin probability that comes from being able to manage the investment portfolio dynamically and purchase annuities.     

Robotics and STEM learning: students’ achievements in assignments according to the P3 Task Taxonomy—practice,problem solving,and projects

This study presents the case of development and evaluation of a STEM-oriented 30-h robotics course for junior high school students (n = 32). Class activities were designed according to the P3 Task Taxonomy, which included: (1) practice—basic closed-ended tasks and exercises; (2) problem solving—small-scale open-ended assignments in which the learner can choose the solution method or arrive at different answers; and (3) project-based learning—open-ended challenging tasks. The research aimed at exploring students’ working patterns, achievements in learning the course, and the impact of this experience on students’ motivation to learn STEM subjects. Evaluation tools included a final exam on factual, procedural and conceptual knowledge in the STEM subject learned in the course, class observations, interviews with the students, and administrating an attitude questionnaire before and after the course. Since the experimental class was quite heterogenic in regard to students’ prior learning achievements and motivation to learn, some of the students completed just the basic exercises, others coped well with the problem-solving tasks, and only a few took it upon themselves to carry out a complex project. However, all students showed high motivation to learn robotics and STEM subjects. In summary, robotics provides a very rich and attractive learning environment for STEM education. Yet, the realization of this potential depends largely on careful design of the course methodology and especially the students’ assignments in the class. One should recognize that often only some students are capable of learning a new subject on their own through project work, and these students also need to gain additional knowledge and skills before dealing with complex projects.     

When marketing and innovation interact: The case of born-global firms

Previous research on born-global firms (BGs) has emphasized their strong dependency on establishing a competitive positioning from the early days of their existence. While many researchers emphasized BGs’ innovativeness as a driver of their competitiveness, the capabilities underlying BGs’ innovativeness are still under-researched, specifically, marketing, and innovation-related capabilities. Based on a preliminary stage of in-depth interviews with senior managers, we identified three capabilities, market intelligence generation, marketing adaptability, and team cohesion, that underscore the interaction between innovation and marketing. We then performed a SEM analysis based on data collected from 127 BGs. Our findings indicate that marketing intelligence and team cohesion directly and positively impact BGs’ innovativeness. Marketing adaptability was found to be moderated by environmental conditions—economic development and technological development. When economic development is high, salesforce adaptability enhances BGs’ innovativeness, while product adaptability or communication adaptability decreases BGs’ innovativeness. When technological development is high, product adaptability enhances BGs’ innovativeness, while salesforce adaptability decreases BGs’ innovativeness.     

A simultaneous-equations analysis of urban development: migration and industrial growth in Israel's new towns

A simultaneous-equations econometric model is used to analyze the recent development of new towns in Israel. The focus is on the relationships among migration, industrial investment, employment, and other structural and policy variables affecting urban development. "Our results affirm the importance of economic opportunity, agglomeration effects, population socioeconomic and ethnic composition, and access in determining migration flows. At the same time, unemployment and investment indices are affected by local labor-market conditions, government incentives, and regional development effects as well as by population composition and migration flows. Policy implications of the analysis are considered."     

Computationally-feasible truthful auctions for convex bundles

In many economic settings, like spectrum and real-estate auctions, geometric figures on the plane are for sale. Each bidder bids for his desired figure, and the auctioneer has to choose a set of disjoint figures that maximizes the social welfare. In this work, we design mechanisms that are both incentive compatible and computationally feasible for these environments. Since the underlying algorithmic problem is computationally hard, these mechanisms cannot always achieve the optimal welfare; Nevertheless, they do guarantee a fraction of the optimal solution. We differentiate between two information models—when both the desired figures and their values are unknown to the auctioneer or when only the agents' values are private data. We guarantee different fractions of the optimal welfare for each information model and for different families of figures (e.g., arbitrary convex figures or axis-aligned rectangles). We suggest using a measure on the geometric diversity of the figures for expressing the quality of the approximations that our mechanisms provide.     

WHAT IS “INSURANCE”? LESSONS FROM THE CAPTIVE INSURANCE TAX CONTROVERSY

Abstract: Over the past 30 years, the tax treatment of insurance premiums paid to captive (i.e., subsidiary) insurance companies has generated considerable controversy and litigation. In this article, we propose a new definition of insurance that is motivated by a careful analysis of the issues raised in the captive insurance tax controversy. Emphasizing the fundamental roles played by market forces and the efficiency of risk transfers, this new definition both broadens and refines traditional definitions of insurance.
