Modelling the inflation process in transition economies: Empirical comparison of Poland, Hungary and Czech Republic

This paper starts from the observation that inflation in transition economies appears to be persistently high and volatile and attempts to provide some empirical characterisation of the inflation process in three such transition economies: Poland, Hungary and Czech Republic. We first consider the role of monetary growth as a major causal factor for inflation in these economies, and argue that the evidence provides rather weak support for the causal relationship. We then propose a transition economy cost-plus model and estimate this using the equilibrium-correction modelling (ECM) strategy augmented by introduction of a number of transitory factors and changes in the internal structure of the real economy which we believe may have had a significant impact on inflation in these economies. We show that this approach enables us to account for long-run inflation in these economies from the early 1980s to the present despite the turbulence of the latter part of the sample period. Our results support wage and exchange rate based inflation policies.     

Enterprising Women,Tourism, and Development: The Case of Bali

Bali, the home of Indonesia’s Hindu minority, is experiencing a rapid growth in tourism and hospitality. The resulting opportunities for small scale, locally owned businesses has greatly benefited women. Using in depth interviews and other supplemental evidence, this trend is examined in order to explore how women are influenced by the circumstances faced, as well as by their culture and heritage. Doing so provides an empirical evidence regarding how women can contribute to the hospitality industry in places such as Bali.     

Are long‐term incentive plans an effective and efficient way of motivating senior executives?

Research on senior executive reward has typically explored the connection between pay, performance and the alignment of interests of executives and shareholders. This article examines the relationship between reward and motivation, drawing on the psychological, behavioural economics and decision‐making literatures. Based on an empirical study of FTSE 350 senior executives, the research examines whether long‐term incentive plans are an effective and efficient way of motivating executives, taking into account risk, time discounting, uncertainty and fairness. The article concludes that the way executives frame choices, perceive value, assess probability, evaluate temporal effects and respond to uncertainty means that long‐term incentive plans (LTIPs) are generally not efficient and are often not effective in meeting their objectives. It proposes that, in its current form, agency theory does not provide a sound basis for modelling senior executive reward, and suggests five areas for development.     

A remark on correlation

Abstract

In the following lines we consider phenomenons which are characterized by t.wo variables x and y, for instance: mariages which are cbaracterized by the age of tbe husband and by thc age of tbe wife. We suppose that we deal with a great frequenoy-distribution of our phenomenon. If we know the law for tbe frequency-distribution of our phenomenon, we could from the analytical form of the law study the different questions, that are of interest for thc statistician.     

On discontinuous frequency-functions and statistical series

Abstract}Y

The ordinary development of the theory of discontinuous frequency-functions is based on the finite expression of the frequency-function. In the present note I shall try to show, that different problems in this theory are more accessible, when we consider the difference equation of the frequency function.     

‘Znakomstva I Svyazi’ (Acquaintances and connections) – Blat,the Soviet Union,and mundane entrepreneurship

The discussion regarding entrepreneurship and society has often presupposed that this society by necessity will be one that embraces the market economy as a guiding principle. This paper questions this assumption by discussing a command economy, namely the Soviet Union, as a fundamentally entrepreneurial society. By introducing the case of the blat, ‘Russia’s economy of favours’, the paper illustrates how mundane individual economies can be a part of entrepreneurship, and how flexible opportunity networks can support the rigidity of a command economy. Continuing from this, the exclusion of such irregular economies is discussed from an ideological rather than an analytic standpoint. The paper further presents some inferences that can be drawn from the case of the blat and which problematizes common assumptions in entrepreneurship studies.     

Modeling node heterogeneity in latent space models for multidimensional networks

Multidimensional network data can have different levels of complexity, as nodes may be characterized by heterogeneous individual-specific features, which may vary across the networks. This article introduces a class of models for multidimensional network data, where different levels of heterogeneity within and between networks can be considered. The proposed framework is developed in the family of latent space models, and it aims to distinguish symmetric relations between the nodes and node-specific features. Model parameters are estimated via a Markov Chain Monte Carlo algorithm. Simulated data and an application to a real example, on fruits import/export data, are used to illustrate and comment on the performance of the proposed models.

Post-Failure Success: Sensemaking in Problem Representation Reformulation

Failure is an inevitable feature of innovation, and management research promulgates the importance of learning from it. Key to excelling at an innovation-based strategy is understanding the processes that can turn failures into successes. However, post-failure success remains elusive. Although failure signals that the innovation journey is off course, shifting trajectory is difficult, because it may require revising assumptions and reformulating the project’s problem representation. Using comparative case studies, this study set out to understand how problem representations are reformulated. Employing case method and comparing data versus theory iteratively, the important role of sensemaking and of leadership behaviors in driving post-failure success became salient. Findings show that problem representations post-failure require a process of problem formulation characterized by sensemaking and that innovative solutions are enabled by the reformulation of problem representations that spring from prospective sensemaking. Furthermore, this article identifies leadership change behavior as the linchpin driving a problem formulation process characterized by prospective sensemaking that catalyzes innovative solutions and explains why some projects thrive post-failure and others do not. This article provides empirical support to the theoretical work of the literature on problem formulation, while extending the learning-from-failure literature by emphasizing and demonstrating the process driving post-failure success. The major implication of our study is that different leadership behaviors may foster different types of sensemaking (retrospective or prospective), and that, in turn, the type of sensemaking matters for how a problem is reformulated. Ultimately, this article concludes that in the context of project failure, problem reformulation that springs from prospective sensemaking enables innovative solutions post-failure.
