ISCAS - Performance and routability improvements for routability-driven FPGA routers
2006 IEEE International Symposium on Circuits and Systems, 1Co-Authors: S.m. Boshra, Hazem M. Abbas, A.m. Darwish, I.e. TalkhanAbstract:Routing FPGAs (Verma, 1999) is a challenging problem because of the Relative Scarcity of routing resources represented in wires and connection points. This can lead either to slow implementations caused by long wiring paths that avoid congestion or a failure to route all signals (McMurchie, 1995). This paper presents some enhancements to improve both the performance and routability of the routability-driven routing using the versatile place and route VPR routing tool (Betz, 1999). Testing MCNC benchmarks has shown the efficiency of these enhancements.

Economic Linkages, Relative Scarcity, and Commodity Futures Returns
SSRN Electronic Journal, 2011Co-Authors: Jaime Casassus, Peng Liu, Ke TangAbstract:This paper shows that economic linkages among commodities create a source of long-term correlation between futures returns. We extend the theory of storage to a multi-commodity level and find that the convenience yield of a commodity depends on its Relative Scarcity with respect to other related commodities. This implies a feedback effect between commodities that is necessary to replicate the upward-sloping correlation term structure of futures returns observed for related commodities. We present a multi-commodity affine model that validates our theoretical predictions and considerably reduces the pricing errors in out-of-sample crack spread options. The Author 2012.

Relative Scarcity of Commodities with a Long-Term Economic Relationship and the Correlation of Futures Returns
2011Co-Authors: Jaime Casassus, Peng Liu, Ke TangAbstract:This paper finds that the long-term co-movement of commodity prices is driven by economic relationships, such as production, substitution, and complementary relationships. Such relationships imply that the convenience yield of a given commodity depends on its Relative Scarcity with respect to associated commodities. The economic linkage between two commodities creates a new source of positive correlation between the futures returns of both commodities. We build an empirical, multi-commodity maximal affine model that allows the convenience yield of a commodity to depend on its Relative Scarcity. We estimate the model using three commodity pairs: heating oil-crude oil, WTI-Brent crude oil and heating oil-gasoline. Our model allows for a flexible correlation term structure of futures returns that matches the upward-sloping patterns observed in the data. The high long-term correlation implied by an economic relationship reduces the volatility of the spread between commodities, which implies lower spread option prices. An out-of-sample test using short-maturity crack spread options data shows that our model considerably reduces the negative bias generated by traditional models.

Relative Scarcity of asthma and atopy among rural adolescents raised on a farm
American Journal of Respiratory and Critical Care Medicine, 2000Co-Authors: Pierre Ernst, Yvon CormierAbstract:We determined the prevalence of markers of atopy and asthma among 1,199 rural secondary school students ages 12 to 19 yr. Subjects identified as having been raised on a farm and half as many subjects without regular exposure to a farming environment from the same school class completed a respiratory symptom questionnaire and underwent allergy skin tests and a methacholine bronchoprovocation test. Current wheeze, airways hyperresponsiveness (AHR), and skin test positivity to inhaled allergens were all significantly less common among adolescents raised on the farm and these differences were especially pronounced in girls. After adjusting for gender and current smoking, the odds ratios for being raised on a farm were: 0.70 (95% CI 0.52 to 0.95) for current wheeze; 0.59 (95% CI 0.37 to 0.95) for asthma, defined as the concomitant occurrence of wheeze and AHR; and 0.58 (95% CI 0.46 to 0.75) for atopy defined as a positive reaction to any one of 24 common inhaled allergens. These associations were also not sign...

profit sharing and the role of professional partnerships
Quarterly Journal of Economics, 2005Co-Authors: Jonathan Levin, Steven TadelisAbstract:When it is hard to assess service quality, firms will suboptimally hire low ability workers. We show that organizing as a profit-sharing partnership can alleviate these problems. Our theory explains the Relative Scarcity of partnerships outside of professional service industries such as law, accounting, medicine, investment banking, architecture, advertising, and consulting. It also sheds light on features of partnerships such as up-or-out promotion systems, the use of noncompete clauses, and recent trends in professional service industries.

A Theory of Partnerships
SSRN Electronic Journal, 2002Co-Authors: Jonathan Levin, Steven TadelisAbstract:We compare the costs and benefits of partnerships Relative to the corporate form of organization. We show that organizing as a partnership can be desirable in human-capital intensive industries where product quality is hard to observe. The theory explains the Relative Scarcity of partnerships outside of professional service industries such as law, accounting, medicine, investment banking, architecture, advertising, and consulting. It also explains features of partnerships such as up-or-out promotion systems, the use of non-compete clauses, motives for profit sharing as well as recent trends in professional service industries.
