Regional relationships between inherent coffee quality and growing environment for denomination of origin labels in Nariño and Cauca,Colombia

International markets are increasingly signaling demand for quality-differentiated coffee, which the Colombian Coffee Growers Federation (FNC) proposed to exploit to identify those regional coffees that would fulfill the requirements to be classified as denomination of origin. The objective of this study was to develop and implement a sound, robust and repeatable approach with and for the FNC to identify regional causal relationships between coffee quality and environmental characteristics as bases for labels of denomination of origin. Environmental differences between coffee-growing areas in the departments of Cauca and Nariño were statistically significant for several characteristics, including the number of dry months, annual precipitation and diurnal temperature range. The dominant varieties (Caturra and Colombia) did not show major differences in quality attributes, and were pooled for the analyses with the environmental data. There are significant differences in biochemical and sensorial product characteristics between the two departments. The spatial patterns in product characteristics exhibit a non-random, regionally-changing structure that is related to those in the environmental data. The generated results provided ample evidence to support the application for regionally-based denominations of origin. Recommendations were derived to help mainstreaming the developed approach and thereby facilitate policy decisions for its use in other geographies and with other crops. Furthermore, the importance of systematic interdisciplinary institutional collaboration for large-scale denomination of origin projects was corroborated for food policy dialogue and decision making. It seems plausible that producers of high-quality products within other commodities are likely to follow the FNC in seeking denomination of origin for their goods. The presented approach is crucial to facilitate policy.     

The ambidextrous CEO

Although most managers publicly acknowledge the need to explore new businesses and markets, the claims of established businesses on company resources almost always come first, especially when times are hard. When top teams allow the tension between core and speculative units to play out at lower levels of management, innovation loses out. At best, leaders of core business units dismiss innovation initiatives as irrelevancies. At worst, they see the new businesses as threats to the firm's core identity and values. Many CEOs take a backseat in debates over resources, ceding much of their power to middle managers, and the company ends up as a collection of feudal baronies. This is a recipe for long-term failure, say the authors. Their research of 12 top management teams at major companies suggests that firms thrive only when senior teams lead ambidextrously--when they foster a state of constant creative conflict between the old and the new. Successful CEOs first develop a broad, forward-looking strategic aspiration that sets ambitious targets both for innovation and core business growth. They then hold the tension between innovation unit demands and core business demands at the very top of the organization. And finally they embrace inconsistency, allowing themselves the latitude to pursue multiple and often conflicting agendas.     

The Conflict Between Conservation and Recreation When Visitors Dislike Crowding: A Theoretical and Empirical Analysis of the Spatial Distribution of Recreational Beach Users

We investigate conflicts between wildlife conservation and recreational use that can occur at open-access sites when visitors dislike crowding. A theoretical model is proposed which determines the spatial distributions of visitors to a beach, given their willingness to walk to avoid crowding and the configuration of beach access points. This model is estimated for three sections of coastline in eastern England using data from aerial video photography. Visitor density is strongly and negatively correlated with distance from access points. Willingness to walk has a highly skewed population distribution. We discuss the implications of these findings for the management of conflicts between conservation and recreation at open-access sites.

货币紧缩和全球房地产泡沫

2005年的世界经济有一个巨大的发展,发生了很多好的事情,也有很多坏的事情.好的事情比如说中国的工业化、印度的工业化,还有很多发展中国家最近四五年里可以赚很多钱,有很多盈余可以偿还他们原来的债务,在五年前我们还在谈到俄国的债务危机、巴西的债务危机,这些国家现在都有很大的盈余,很多发展中国家现在的情况是历史上最好的,从来没有过的.     

NONLINEAR BUSINESS CYCLE MODELLING

Abstract. Literature which employs nonlinearities to explain economic fluctuations, commonly called business cycles, is surveyed. Relaxation of the linearity assumption significantly increases the range of possible dynamic solution paths and introduces the possibility that business cycles are endogenously determined. The dominant post-war modelling strategy has been the Frisch (1933) (and Slutsky, 1937) inspired one of developing essentially (log) linear economic models which produce damped cycles (or monotonic damping) to propagate the energy provided by repeated random (or autocorrelated) shocks. The cycle is exogenously driven, since it would die out in the absence of shocks. Deterministic (nonstochastic) nonlinear models can produce a wide range of endogenous fluctuations, including: stable limit cycles; growth cycles; and chaotic output, which have the appearance of random fluctuations. Further, the same model can produce qualitatively different outputs according to starting and parameter values. If the possibility of shocks to parameters is admitted, then behaviour can change abruptly following shocks. Evidence on the existence of nonlinearities and chaos in macroeconomic time series is assessed and alternative approaches to modelling dynamic economic development, related to the work of Keynes, Marx, Schumpeter and Shackle, are discussed. Their ideas have not proved readily amenable to mathematical modelling, but attempts to encapsulate some of them are reviewed.     

Dysfunctional Effects of League Tables: A Comparison Between English and Scottish Primary Schools

League tables based on Key Performance Indicators (KPIs) have become an important part of the management of the UK's education system. While the performance measured by KPIs has apparently improved, concerns have been raised that they may have unintended or dysfunctional effects. This article compares English with Scottish schools. The authors found that English primary schools perceive their KPI systems (with league tables), as being significantly more dysfunctional than those of their Scottish counterparts (without tables). The article provides empirical evidence to support the many arguments that high-stakes single proxy indicators can have significant dysfunctional effects.     

The Dynamics of REIT Capital Flows and Returns

This study examines the effects of capital flows into the REIT sector on REIT returns and, simultaneously, the effects of REIT returns on subsequent REIT capital flows. The dynamic relation between REIT capital flows and returns is estimated using vector autoregression (VAR) techniques. Unlike static regression techniques, our dynamic model produces estimates of the short-run relationships, long-run relationships, impulse response functions and forecast variance decompositions. We find evidence that REIT equity flows are significantly positively related to the prior quarter's flows and negatively related to flows from two quarters ago. The evidence on the responsiveness of flows to prior returns is time-period specific. In the important post-1992 subperiod, REIT returns do not significantly affect REIT flows in any of the VAR model specifications. Simultaneously, REIT capital flows do appear to have a significant influence on equity REIT returns.     

Edith Penrose's Contributions to the Resource-based View: An Alternative Perspective

ABSTRACT Edith Penrose's work has been widely acknowledged to have played a central role in providing the intellectual foundations of the resource‐based view. This position, however, was recently challenged in a paper by Rugman and Verbeke (2002 ). In this paper we address the three main arguments of Rugman and Verbeke and, by drawing on her writings, demonstrate that their arguments are materially incorrect. While readily conceding that Penrose's primary goal was to explain the growth of firms, we show that her analysis of path‐dependent firm evolution anticipated many key propositions of the resource‐based view.
