A NEW MULTIPLICATIVE DECOMPOSITION FOR THE FOSTER–GREER–THORBECKE POVERTY INDICES

This paper shows that Foster–Greer–Thorbecke poverty indices can be written as the product of components summarizing the incidence, intensity and inequality dimensions of poverty and provides an empirical illustration of the decomposition using Spanish household budget surveys data.     

Multiple versus Single Banking Relationships: Theory and Evidence

A theory of the optimal number of banking relationships is developed and tested using matched bank-firm data. According to the theory, relationship banks may be unable to continue funding profitable projects owing to internal problems and a firm may thus have to refinance from nonrelationship banks. The latter, however, face an adverse selection problem, as they do not know the quality of the project, and may refuse to lend. In these circumstances, multiple banking can reduce the probability of an early liquidation of the project. The empirical evidence supports the predictions of the model.     

Technological Regimes and Schumpeterian Patterns of Innovation

This paper proposes that the specific pattern of innovative activities in an industry can be explained as the outcome of different technological (learning) regimes . A technological regime is defined by the particular combination of technological opportunities, appropriability of innovations, cumulativeness of technical advances and properties of the knowledge base. Building upon the distinction between Schumpeter Mark I and Schumpeter Mark II industries, this paper provides empirical estimates of the relationships between indicators of the Schumpeterian patterns of innovation (concentration of innovative activities, stability in the hierarchy of innovators and importance of new innovators) and indicators of the variables defining technological regimes.     

RISK MEASURES: RATIONALITY AND DIVERSIFICATION

When there is uncertainty about interest rates (typically due to either illiquidity or defaultability of zero coupon bonds) the cash‐additivity assumption on risk measures becomes problematic. When this assumption is weakened, to cash‐subadditivity for example, the equivalence between convexity and the diversification principle no longer holds. In fact, this principle only implies (and it is implied by) quasiconvexity. For this reason, in this paper quasiconvex risk measures are studied. We provide a dual characterization of quasiconvex cash‐subadditive risk measures and we establish necessary and sufficient conditions for their law invariance. As a byproduct, we obtain an alternative characterization of the actuarial mean value premium principle.     

Market Orientation and R&D Effectiveness in High‐Technology Firms: An Empirical Investigation in the Biotechnology Industry*

There seems to be lack of consensus among informed scholars about the importance a of market orientation for high‐technology firms. This paper gives a comprehensive review of existing empirical studies on the relationship between market orientation and innovation performance and pinpoints two limitations in this research stream that might be at the origin of such controversy. First, extant research often overlooked key innovation outcomes for high‐technology firms, such as those related to research and development (R&D) performance. Second, organizational conditions that can ensure an optimal integration of market knowledge in the innovation process have been less analyzed in the case of these firms. Against this background, the present study contributes to the literature by providing a test of the effect of market orientation on R&D effectiveness and the moderating role of knowledge integration in this relationship, using a sample of Italian biotechnology firms. The study's objectives are addressed in two steps. The first one consists of an in‐depth qualitative study based on semistructured interviews in five biotechnology firms. The second step consists of a follow‐up survey of 50 biotechnology firms. Results from hierarchical multiple regression analysis show that the different dimensions of a market orientation have diverse effects on R&D effectiveness of high‐technology firms: whereas interfunctional coordination has a positive main effect, the effect of customer orientation is moderated by knowledge integration, and competitor orientation has no effect on R&D effectiveness. Post hoc analyses also show two additional results involving a broader set of dependent variables. First, R&D effectiveness mediates the effects of customer orientation and interfunctional coordination on organizational performance. Second, market orientation does not appear to significantly affect R&D efficiency. The present study contributes to current literature in two main respects. First, it adds to previous work on market orientation and innovation by proposing a new dependent variable—R&D effectiveness—which offers a better perspective to understand the impact of market orientation on innovation performance in high‐technology contexts. Second, while part of the current debate on the role of market orientation in high‐tech markets seems to be polarized by positions that sustain its potential drawbacks or, on the contrary, its advantages, this study's findings on the moderating role of knowledge integration shed light on important contingency factors, such as organizational capabilities. The authors discuss the study's limitations and provide directions for future research.

A note on contribution games with loss functions

Decisions on joint funding of continuous public goods between two agents often involve heterogeneous targets. We introduce loss functions in a contribution game in order to study the effect of this conflict. Unlike Varian (1994), joint contribution occurs only if the players’ targets are sufficiently close and the sequential game reduces free riding problems, while total contribution is higher in the simultaneous game.     

数字经济对产业结构升级的影响研究——基于创新产出角度的分析

作为经济增长新动能,数字经济已经成为推进共同富裕的重要力量。文章采用熵值法和耦合协调度模型结合莫兰指数模型,构建数字经济−共同富裕评估指标体系,对我国30个省份2013—2021年数字经济与共同富裕的耦合协调机理及时空动态演进展开实证研究。研究显示：（1）我国数字经济与共同富裕发展水平总体上稳步增长,且东部＞中部＞东北＞西部地区;（2）我国数字经济与共同富裕耦合协调水平呈现中部地区高度耦合、其他地区为“拮抗−磨合−高水平耦合”的上升趋势;（3）数字经济与共同富裕耦合协调度在空间上存在正相关演进趋势,表现为“高高”和“低低”的空间集聚分布特征。为发展数字经济以推动共同富裕目标的实现,政府要加强数字化基础设施建设和数字技术培训、促进传统产业转型升级、优化资源配置等。

     

Assessing skewness in financial markets

It is a matter of common observation that investors value substantial gains but are averse to heavy losses. Obvious as it may sound, this translates into an interesting preference for right-skewed return distributions, whose right tails are heavier than their left tails. Skewness is thus not only a way to describe the shape of a distribution, but also a tool for risk measurement. We review the statistical literature on skewness and provide a comprehensive framework for its assessment. Then, we present a new measure of skewness, based on the decomposition of variance in its upward and downward components. We argue that this measure fills a gap in the literature and show in a simulation study that it strikes a good balance between robustness and sensitivity.     

Integrated reporting and cost of capital: The moderating role of cultural dimensions

Since its introduction, integrated reporting (IR) has triggered a rich debate covering several aspects, from the structure and the features of a document to the effects of its publication. Very recently, scholars have examined the negative relationship between IR and the cost of capital for firms, completely missing the opportunity to understand whether this fact is contingent on the cultural context that adopting companies operate in. We fill this gap by resorting to a panel sample of 211 adopters from 31 countries over the period spanning 2009–2017, counting 1,455 observations. Our evidence confirms that adopters, on average, benefit from a 1.4% decrease in the cost of capital. Yet, more importantly, IR effectiveness is exalted in countries with low power distance, strong collectivism values, and high level of masculinity, while uncertainty avoidance, long‐term orientation, and indulgence do not seem to play any moderating role.
