The sophistication of regional economic models has been demonstrated in numerous ways, most recently in the form of linking several modeling systems or in the expansion in the number of equations that can be manipulated successfully to produce impact analyses or forecasts. In this paper, an alternative perspective is employed. What do regional macro-level forecasts indicate about the process of structural change? A new methodology is illustrated that enables analysts to make forecasts of detailed structural change in the interindustry relations in an economy. Using a regional econometric input-output model developed for the Chicago metropolitan region, derived input-output tables are extracted for the period 1975–2016. These tables are then analyzed to determine the forecasted direction of structural changes for the region. The innovation illustrated here is based on a model that exploits the general equilibrium spirit of computable general equilibrium models through the adjustment of input coefficients to clear markets. 相似文献

If negotiations produce an end to the Israeli–Palestinian conflict then a sovereign, independent Palestine may emerge. But what is required for it to succeed? Nothing is more important than the security of a Palestinian state–for itself, for Israel, and for the region: security trumps all else. In addition to the problem of dealing effectively with opposition to a peace agreement within Palestine or directed against it from outside, the nature and magnitude of the security challenge will depend in large part on three issues: the drawing of borders between Israel and Palestine–and whether they are porous or marked by a rigid line of barriers; whether Israeli settlements are withdrawn, or in part incorporated into Israel, perhaps through land swaps with Palestine; and what arrangements are made for Jerusalem. One answer is the creation of effective Palestinian military forces (in addition to police), but this course could be divisive; a second is the development of a series of Israeli–Palestinian confidence‐building and share–security measures, including intelligence cooperation; a third is progress towards reducing external threats to Israel–Palestine, including success in Iraq and in defusing other Middle East problems. Most useful, however, would be the creation of an American‐led peace enabling force, ideally modelled on NATO. This force would need to be agreed by both Israel and Palestine; it must be adequately staffed, trained and equipped; its duties and rules of engagement must make sense to all parties; and it must be part of a network of dispute‐resolution and confidence‐building measures in full partnership with Israeli and Palestinian authorities. 相似文献

There is a long history of human interaction with plants of the Aroideae subfamily (Araceae). Despite these plants' chemical defenses against animal and vegetal predation, humans have targeted their starchy corms, tubers and rhizomes for dietary purposes. In the Eastern Woodlands of North America, early Europeans described the Native population as utilizing the highly acridic Peltandra virginica (arrow arum) for subsistence needs. In order to render this resource edible, however, the acridic principle first needs to be eliminated. Our study investigates the affect these processing activities have on the integrity of arrow arum starch grains. Findings from this study demonstrate that environmental variables specific to individual processing procedures may be more influential on starch grain survival than simply the temperatures reached during cooking. 相似文献
