We present a decentralized market-based approach to resource allocation in a heterogeneous overlay network. This resource allocation strategy dynamically assigns resources in an overlay network to requests for service based on current system utilization, thus enabling the system to accommodate fluctuating demand for its resources. Our approach is based on a mathematical model of this resource a...

Resource allocation plays a critical role to enhance the performance of cognitive orthogonal frequency division multiplexing (OFDM) network. However, due to lack the cooperation between cognitive network and primary network, the channel state information (CSI) between cognitive radio (CR) user and primary user (PU) could not be estimated precisely. In this work, a resource allocation problem ov...

This paper considers the bandwidth allocation problem for an Ethernet Passive Optical Network (EPON). An EPON is one of the best options for high-speed access networks. This paper formulates the optimal bandwidth allocation problem with an analytical model to maximize throughput and weighted fairness simultaneously. First, the optimal solution under certain conditions is characterized. Then, tw...

Climate change policies can regulate greenhouse gases (GHG) at a variety of points in the product cycle of fossil fuels: from fossil fuel suppliers based on the carbon content of extracted fossil resource to nal emitters at the point of energy generation. This paper develops a general equilibrium model with trade between fossil resource abundant countries and capital abundant countries to show ...

Using a database of branch managers in retail banks, this study finds some empirical support for the two main predictions of Jensen and Meckling’s (1992) theory on organizational design choices: a) the allocation of decision rights to branch managers is associated with control systems that measure their performance and reward them based on these performance measures, and b) these decision right...

Public health advocates and scientists working on obesity prevention policy face challenges in balancing legal rights, individual freedom, and societal health goals. In particular, the US Constitution and the 50 state constitutions place limits on the ability of government to act, even in the best interests of the public. To help policymakers avoid crossing constitutional boundaries, we distill...

Corruption has different efficiency effects across countries. Conventional economic models of corruption are shown to be deficient in explaining these differences. Instead the article suggests that the distribution of power within the patron-client networks in which corruption is taking place is an important variable explaining the differences in the efficiency effects of corruption. Where patr...

We study the investment analyses of 67 portfolio investments by 11 venture capital (VC) firms. VCs describe the strengths and risks of the investments as well as expected postinvestment actions. We classify the risks into three categories and relate them to the allocation of cash flow rights, contingencies, control rights, and liquidation rights between VCs and entrepreneurs. The risk results s...
