A modification of a well-known shipments test for geographic market definition may be useful in identifying antitrust markets. By recognizing the possible significance of a high LIFO value and a notably lower LOFI value, and searching for possible barriers to product entry that could explain the asymmetry, analysts can reduce the chances of adopting an overly broad geographic market. This is illustrated by comparing the results from applying the shipments test to those from residual demand estimations, and by reviewing the evidence and findings in several recent antitrust proceedings in light of the asymmetric shipments patterns they report. 相似文献

World inflation is being held down by emerging market competition interacting with continuing OECD monetary policy. Here at home, fast productivity growth makes the UK something of an emerging market within Europe. 相似文献

A simple open-economy AK model with collateral constraints accounts for growth breaks and growth-reversal episodes, during which countries face abrupt
changes in their growth rate that may lead to either growth miracles or growth disasters. Absent commitment to investment
by the borrowing country, imperfect contract enforcement leads to an informational lag such that the debt contracted upon
today depends upon the past stock of capital. The no-commitment delay originates a history effect by which the richer a country has been in the past, the more it can borrow today. For (arbitrarily) small delays,
the history effect offsets the growth benefits from international borrowing and dampens growth, and it leads to both leapfrogging
in long-run levels and growth breaks. When large enough, the history effect originates growth reversals and we connect the
latter to leapfrogging. Finally, we argue that the model accords with the reported evidence on changes in the growth rate
at break dates. We also provide examples showing that leapfrogging and growth reversals may coexist, so that currently poor
but fast-growing countries experiencing sharp growth reversals may end up, in the long-run, significantly richer than currently
rich but declining countries. 相似文献

Most research on new product and service development by entrepreneurial firms takes an individual‐level, prelaunch perspective or firm‐level postlaunch perspective. Our study examines two components of the new product and service introduction process: how entrepreneurs' prior knowledge underpins (1) firm technological innovation prior to the introduction of new products and services (prelaunch) and (2) postlaunch viability of those new products and services. Our findings, based on a series of analyses of data from 158 entrepreneurial firms, show that formal technological innovation fully mediates the relation between prior knowledge and the introduction of viable new products and services. 相似文献

The possible contribution of local sales chains to the reduction of energy consumption has been hotly debated in recent years. Some authors establish a link between the reduction of distances traveled by food and lower energy consumption due to transportation, while others hold that local supply chains have a poor energy performance. This article engages this debate by comparing the rates of energy consumption attributable to different modes of distribution of fruits and vegetables in a region of France. 相似文献

Most industrial countries have experienced a transformation of land use: from decreasing to expanding forest areas, the so-called forest transition. Outside closed forests, European rural landscapes exhibit a diversity of tree-based agricultural systems, but the question of whether this forest transition has also affected ‘trees outside forests’ has rarely been studied. The aim of this study is to analyze the spatial-temporal dynamics of farm trees and woodlands in an agricultural landscape in Eastern Germany from 1964 to 2008, based on aerial photographs and digital orthophotos. Taking a landscape ecological perspective, we quantify farm tree dynamics, disentangle processes of gain and loss in the socialist and post-socialist periods of Eastern Germany, and assess differences in ecosystem services provided by farm trees. A substantial increase of overall tree cover by 24.8% was observed for the selected time period, but trajectories have been disparate across different farm tree classes. The increase in tree cover was stronger in steep valleys than on hills and plateaus, indicating a significant interdependence between topography and trajectories of change. Patch numbers of farm trees did not increase, which suggests that the expansion of tree cover is mostly due to a spatial expansion of previously existing tree patches. Overall net gains in tree cover were rather similar during the socialist and post-socialist eras. The general increase in tree cover was accompanied by increase in agriculture-related ecosystem service provision, but the increase in pollination and pest control services was much lower than that in water purification services. These findings present the first empirical evidence from an industrialized country that there is also an ongoing ‘forest transition’ outside closed forests. Potential, partially counteracting drivers of change during the socialist and post-socialist periods have mainly been related to farm policies and the environmental consciousness of land users and society as a whole. 相似文献

Top managers tend to focus on strategy formulation and planning but fail to embrace the problem-solving complexity of strategy implementation. This can lead to implementation failures that are reflected in misaligned organizations that seem to know where they want to go but cannot seem to get there. We posit that one reason for the ineffective transition from strategy formulation to strategy implementation is that planning is associated with a different set of thought processes and emotional experiences than is required for strategy implementation. We integrate research from management (strategy implementation and change management) with that from psychology (self-regulation and nudges) to identify the transition from strategic planning to implementation as a roadblock that prevents effective strategy implementation. We then present six leadership nudges that aid this transition. The first set of nudges are willpower-enhancing nudges that rely on increasing willpower to help transition from planning to implementation: Remove the distraction to plan, develop implementation intentions, and use verbal framing. The second set are desire-reducing nudges that work to decrease the desirability of planning and in so doing facilitate the transition to implementation: Highlight the end game, leverage a crisis, and celebrate small wins. 相似文献
