Innovation and imitation as an interactive process

This article deals with the problem of the coexistence of innovators and imitators in a competitive market. The study proposes a model of innovation and diffusion of productive knowledge as an interactive process between innovators and imitators under conditions of dynamic uncertainty. The process can be modelled as a Stackelberg game, where the innovator acts as a leader in choosing whether to share knowledge or set up private protection and the imitator as a follower in choosing when becoming active. Under these conditions, activation thresholds are derived for both innovators and imitators. If protection policies are effective, the imitator can be trapped into an inaction region by the innovator. Thus, there will be two regimes without and with diffusion, according to whether the inaction region is enacted or not. Under these conditions, discovery and diffusion appear to be dynamic complements, as a higher speed of activation of innovating firms is favoured by a higher level of imitation and a higher speed of activation of imitating firms is favoured by a higher level of discoveries. In order to explore some of the quantitative implications of these results, the paper also proposes an application of the model to four European countries.     

Exploration of congruence in perceptions of buyer–supplier attraction: A dyadic multiple case study

In long-term complex buyer–supplier relationships, many exchanges are non-contractual, a factor that emphasizes the social dimension of the relationship. Previous studies have shown that attraction is a fundamental aspect of the social dimension and a main driver in non-contractual exchanges. Although attraction is a determinant of a relationship, many studies have examined the relationship only from the buyer's or supplier's perspective. Our study extends this research stream by considering the dyadic aspect of attraction and poses the following questions: Does the success of a relationship require that both parties perceive it to be attractive? How important is it to understand how the company looks in the eyes of the other party? In this paper, we explore the dyadic aspect of buyer–supplier attraction by analyzing six cases, two buyer firms and six supplier firms and by conducting a total of 43 interviews. By using cross-case analyses, we develop a set of proposals for explaining how congruence in perceptions of attraction affects relationship success.     

Job demands–resources: a gender perspective on employee well-being and resilience in retail stores in China

Abstract

Organisational resilience can be promoted through human resource management (HRM) practices that enhance individual employees’ well-being and ability to cope with adversity. However, the extant literature tends to neglect the influence of gender on employee well-being and resilience. Shop floor employees in retail stores often undertake demanding roles, characterised by considerable pressure and low pay, and attendant high levels of employee turnover. Drawing on the job demands–resources model, by analysing data collected from 697 employees at foreign-invested retail stores in China, this paper found that workload and employee participation in decision-making had a similar impact on the well-being of both male and female employees. However, the impact of job security and emotional demands on employees differed by gender. This paper extends the job demands–resources model by articulating the influence of gender on employee well-being. Additionally, its empirical insights, drawn from an emerging economy context, enable a contribution to the literature on employee well-being and resilience. Relevant implications for HRM and resilience are discussed.     

Lessons from a century of FED policy: Why monetary and credit policies need rules and boundaries

Wide operational and financial independence given to monetary and credit policies subjects the Federal Reserve to incentives detrimental for macroeconomic and financial stability. The absence of a monetary policy rule created go-stop incentives that produced inefficient volatility of both inflation and unemployment during the Great Inflation. Fed credit policy has undergone massive “mission creep” since the Fed was established. Being debt-financed fiscal policy, Fed credit policy beyond ordinary temporary lending to solvent depositories creates friction with the fiscal authorities and jeopardizes the Fed׳s independence. An ambiguous boundary of expansive Fed credit policy creates expectations of Fed accommodation in financial crisis—that blunts the incentive of private entities to take protective measures beforehand (to shrink counter-party risk and reliance on short-term finance, and build up equity capital) and blunts the incentive of the fiscal authorities to prepare procedures in advance to act systematically in times of credit turmoil. These points are illustrated with reference to the 2007–09 financial crisis. Part of the problem is that the independent Fed does not have the same incentive as the 19th century Bank of England to follow Bagehot׳s Rule. The paper concludes with a set of principles to preserve a workable, sustainable division of responsibilities between the independent central bank and the fiscal authorities.     

Some Relationships between T-Accounts,Input–Output Tables and Social Accounting Matrices

Some relationships between the T-accounting format for presenting commodity balances; input–output (IO) tables; and social accounting matrices are discussed in this paper. The starting point is to recognize that IO tables do not contain all the information that is needed to complete a social accounting matrix (SAM), or, therefore, for the modelling of phenomena that depend on having a fully articulated SAM, such as the interdependence of the distribution of income and the structure of production. There is a need, therefore, to establish the character of the extra information that is required and this can be achieved by imposing the requirement that a SAM should be consistent with the basic cash identity that is fundamental to all social accounting. A second agendum is to develop the argument that, while T-accounts can, in principle, provide a database equivalent to that of a SAM, in practice, they are typically found to be an imperfect substitute. It is important, therefore, in designing a database, to go beyond the confines of an (extended) IO system and T-accounts. SAMs provide an appropriate framework for doing so.     

Antecedents of work–life involvement in work–life issues: institutional pressures,efficiency gains or both?

This paper contributes to the literature by integrating relevant insights from institutional theory and expected efficiency gains to explain organisational responsiveness to work–life issues. In times of global crisis it seems relevant to explore both the question of whether institutional pressures influence organisational behaviour and the positive and negative consequences implementing work–life practices. We tested the model using survey data from 146 private Spanish firms in two different industries. Hierarchical regression analyses tested the relationship between institutional pressures and organisational responsiveness and the potential moderator effect of the expected efficiency gains. The results reveal that mimetic and particular normative pressures significantly influence work–life practices, while coercive and global normative pressures appear not to do so. The perception of certain negative consequences related to the implementation of work–life practices inhibits this responsiveness. The positive outcomes are only relevant for the moderating effect they have on the relationship between institutional pressures and work–life responsiveness.     

Analysis of ruin measures for the classical compound Poisson risk model with dependence

In this paper, we consider an extension to the classical compound Poisson risk model. Historically, it has been assumed that the claim amounts and claim inter-arrival times are independent. In this contribution, a dependence structure between the claim amount and the interclaim time is introduced through a Farlie–Gumbel–Morgenstern copula. In this framework, we derive the integro-differential equation and the Laplace transform (LT) of the Gerber–Shiu discounted penalty function. An explicit expression for the LT of the discounted value of a general function of the deficit at ruin is obtained for claim amounts having an exponential distribution.     

US and East Asian Security under the Obama Presidency: A Japanese Perspective

The most important factor determining the structure of East Asia will continue to be the strategic relationship between the USA and China. It is the key component of the six party talks on the North Korean problem as well as nuclear nonproliferation. Japan is obviously a lesser strategic player, which is in a position to encourage middle-power security cooperation among the East Asian countries breathing between the USA and China. There is a conceptual, if not geopolitical, competition between Japan and China over an ideal future of East Asian regionalism, which the East Asian countries and the USA should join in a constructive manner.     

HOW MUCH DO EXPORTS CONTRIBUTE TO CHINA'S INCOME GROWTH?

It is a widespread belief that exports, in particular of ‘high-tech’ products, contribute much to China's income growth. This study addresses this issue by applying a structural decomposition analysis to input–output (I–O) data. We employ two extended I–O tables that distinguish processing trade from ordinary exports. The contribution of exports to the value-added growth from 2002 to 2007 is found to be overestimated by 32% when standard I–O tables are used rather than the extended I–O tables. Even more strikingly, the value-added growth that may be attributed to the exports of ‘high-tech’ telecommunication products is overestimated by no less than 63%. A serious overestimation of the contribution to income growth of certain products (such as high-tech products) sends out misleading signals to policymakers. When measured correctly, the true contribution appears to be substantially smaller than is generally believed to be.     

Testing for mutually exciting jumps and financial flights in high frequency data

We propose a new nonparametric test to identify mutually exciting jumps in high frequency data. We derive the asymptotic properties of the test statistics and show that the tests have good size and reasonable power in finite sample cases. Using our mutual excitation tests, we empirically characterize the dynamics of financial flights in forms of flight-to-safety and flight-to-quality. The results indicate that mutually exciting jumps and risk-off trades mostly occur in periods of high market stress. Flight-to-safety episodes (from stocks to gold) arrive more frequently than do flight-to-quality spells (from stocks to bonds). We further find evidence that reverse cross-excitations or seeking-return-strategies exhibit significant asymmetry over the business cycle, reflecting the fact that investors appear to be selling gold – rather than bonds – to invest in stocks during good market conditions.
