The Economics Of Yield-Driven Processes, Roger E. Bohn, Christian Terwiesch Dec 1999

The Economics Of Yield-Driven Processes, Roger E. Bohn, Christian Terwiesch

Operations, Information and Decisions Papers

The economic performance of many modern production processes is substantially influenced by process yields. Their first effect is on product cost — in some cases, low-yields can cause costs to double or worse. Yet measuring only costs can substantially underestimate the importance of yield improvement. We show that yields are especially important in periods of constrained capacity, such as new product ramp-up. Our analysis is illustrated with numerical examples taken from hard disk drive manufacturing. A three percentage point increase in yields can be worth about 6% of gross revenue and 17% of contribution. In fact, an eight percentage point improvement ...


Selección Empírica Para El Desarrollo Económico Regional, Vicente German-Soto Oct 1999

Selección Empírica Para El Desarrollo Económico Regional, Vicente German-Soto

Vicente German-Soto

This work disscuses aspects linked to identification of the important sectors through the input-output coefficients for the regional levels of the economies. We base our empirical evidence in a technology structure derivated of that sectors pushing of final demand. Results reflect that a unique method method to select important sectors does not exist. An final demand index selects to commercial sector as the most important. Sectors wiht the highest index correspond to activities highly dependent of the government.


Institutional Changes And Discretionary Value For Property Rights In Drylands’ Farming Of The Sudan, Professor Issam A.W. Mohamed Jun 1999

Institutional Changes And Discretionary Value For Property Rights In Drylands’ Farming Of The Sudan, Professor Issam A.W. Mohamed

Professor Issam A.W. Mohamed

Research on land tenure and use control and the socioeconomic sets of regulations in the agricultural rainfed sub sector of Sudan, come to focus for many reasons. Anthropogenic pressure, expanding animal population and migration led to accelerated impacts on both the ecological systems and land yields. Conflicts between governmental regulations and indigenous rules contribute to generate inconsistencies on who have the right to till the land and hence own it. With such transformation logically, more intensive commercial farming took place and land intake exponentially increased. Private or collective property rights of land are procured through traditional tenure, prescription, settlement or ...


The Great Transition: The Dynamics Of Market Transitions And The Case Of Russia, 1991-1995, Jeffrey K. Hass Jun 1999

The Great Transition: The Dynamics Of Market Transitions And The Case Of Russia, 1991-1995, Jeffrey K. Hass

Sociology and Anthropology Faculty Publications

The market transition in Eastern Europe and the former Soviet Union brings us back to essential issues that Marx and Weber addressed: the genesis of capitalism and the process of economic change. What is the transition and what does it involve - restructuring incentives, creating new laws, learning new culture, or creating new power structures? The answer partially depends on the particular transition (initial conditions, targets, actors' perceptions); but necessary general frameworks remain elusive, and current economic policies and analyses reveal that we understand little more about economic change than a century ago. Recent works on market transitions have furthered our ...


Nonlinear Income Effects In Random Utility Models, Joseph A. Herriges, Catherine L. Kling Feb 1999

Nonlinear Income Effects In Random Utility Models, Joseph A. Herriges, Catherine L. Kling

Economics Publications

Random utility models (RUMs) are used in the literature to model consumer choices from among a discrete set of alternatives, and they typically impose a constant marginal utility of income on individual preferences. This assumption is driven partially by the difficulty of constructing welfare estimates in models with nonlinear income effects. Recently, McFadden (1995) developed an algorithm for computing these welfare impacts using a Monte Carlo Markov chain simulator for generalized extreme-value variates. This paper investigates the empirical consequences of nonlinear RUMs in the case of sportfishing modal choice, while refining and contrasting the available methods for welfare estimation.


Revegetating Desert Plant Communities, David A. Bainbridge Jan 1999

Revegetating Desert Plant Communities, David A. Bainbridge

David A Bainbridge

Desert revegetation is possible but not easy. Careful attention to plant production (root:shoot), site prep, planting, irrigation and aftercare can lead to good survival even under extreme desert conditions. Cost per survivor is a critical consideration.


Soil Pitting For Revegetation, David A. Bainbridge Jan 1999

Soil Pitting For Revegetation, David A. Bainbridge

David A Bainbridge

Soil pitting provides many benefits in ecological restoration of degraded lands. The pits capture rainwater, trap seeds and soil symbionts and protect seedlings from windblast.


Arkansas Gray Fox Fur Price-Harvest Model Revisited, Peta Elsken-Lacy, Amy M. Wilson, Gary A. Heidt, James H. Peck Jan 1999

Arkansas Gray Fox Fur Price-Harvest Model Revisited, Peta Elsken-Lacy, Amy M. Wilson, Gary A. Heidt, James H. Peck

Journal of the Arkansas Academy of Science

Peck and Heidt (1985) proposed a linear model that demonstrated that for gray fox (Urocyon cinereoargenteus) in Arkansas; total fur harvests from 1966-1982 were highly correlated with mean pelt values. Single variable models using linear regression analysis of current season pelt values (CSPV) and previous season pelt values (PSPV) were designed to predict total fur harvests. These models demonstrated high correlations (r =0.93 and 0.89, respectively). In the past 15 years, markets for fur have undergone many perturbations within Arkansas and overseas resulting in great changes in mean pelt prices. In an attempt to evaluate the continued performance ...

Measures Of Welfare Effects In Multiproduct Industries: The Case Of Multispecies Individual Quota Fisheries, Niels Vestergaard Dec 1998

Measures Of Welfare Effects In Multiproduct Industries: The Case Of Multispecies Individual Quota Fisheries, Niels Vestergaard

Niels Vestergaard

A framework is developed to measure the welfare effects of individual quota reforms in multiproduct industries using the multimarket welfare measure techniques suggested by Just, Hueth, and Schmitz (1982) and the concept of virtual price in the production theory literature (Neary 1995; Squires and Kirkley 1996). Under joint in input production it shown that quasirent under a single quota can be measured by the producer surplus either in the output market for quota output or in the quota market. Under multiple quotas the welfare effects of quota policies can be measured in one of the quota markets using inverse derived ...
