A model of population distribution,traffic congestion,and neighborhood crowding in a circular city

An idealized static equilibrium model of a circularly symmetric city is presented. The model allows one to compute the spatial distribution of residences, given certain simple and plausible assumptions about the “costs” of transport, housing and neighborhood crowding. The model is chosen so as to guarantee that in first approximation, the residential population distribution which would be considered optimal by a perfect planner is identical to the distribution reached in a push-shove, laissez-faire equilibrium. This aspect of the construction is shown to be related in a simple way to the familiar “external diseconomy” situation in which a free resource is allocated among alternative uses by equating average, rather than marginal products. The existence of an infinite class of models in which the associated planner's optimum and laissez-faire equilibria are equivalent follows naturally from the standard theory of the private and social costs of highway congestion. The model leads naturally to exponentially falling population distributions which exhibit an “urban-suburban” dichotomy, to a particular overall city size, and to an optimal allocation of land between transport and residential uses.     

Financial risk taking in the presence of correlated non-financial background risk

This paper characterizes the stochastic deterioration resulting from taking a zero-mean financial risk in the presence of correlated non-financial background risk. We show in particular that it has an equivalent stochastic order as well as a necessary and sufficient “integral condition” that implies and is implied by a particular sense in which the stochastic deterioration can be decomposed into a “correlation increase” and a “marginal risk increase”. We further characterize a measure of aversion to the stochastic deterioration. These characterizations provide for a more general framework for formulating concepts of increases in risk and correlation and for better understanding risk management decisions governed by individuals’ attitudes to them.     

A system for evaluating social welfare programs and allocating contributed resources based on citizen input

This paper describes the development and implementation of a social welfare program evaluation system developed by a Community Council to aid the resource allocation decision process of a local United Way. The system assigns a “utility” measure to each program based on how the program satisfies the long-term social welfare goals of the community adjusted for the effect of short range, time dependent criteria affecting the region. Data for the processes described was obtained by quantifying the subjective feelings of the individual members of the Community Council. The results have been accepted by the United Way Organization and are currently being used to assist in the planning and resource allocation functions of the fund.

Forecasting volatility with time-varying leverage and volatility of volatility effects

Predicting volatility is of primary importance for business applications in risk management, asset allocation, and the pricing of derivative instruments. This paper proposes a measurement model that considers the possibly time-varying interaction of realized volatility and asset returns according to a bivariate model to capture its major characteristics: (i) the long-term memory of the volatility process, (ii) the heavy-tailedness of the distribution of returns, and (iii) the negative dependence of volatility and daily market returns. We assess the relevance of the effects of “the volatility of volatility” and time-varying “leverage” to the out-of-sample forecasting performance of the model, and evaluate the density of forecasts of market volatility. Empirical results show that our specification can outperform the benchmark HAR–GARCH model in terms of both point and density forecasts.     

Modeling emergency evacuation with time and resource constraints: A case study from Gujarat

This study develops an off-site emergency response plan for a nuclear power plant in Gujarat, India subject to time constraints with resource limitations and risk of radiation exposure to victims. We formulate an optimization model to capture the effect of delay in evacuation, limited resource availability, and costs associated with resource allocation. A single chain closed queuing network model with class switching is used to model traffic congestion during evacuation. The throughput measures from the queuing network are used as inputs in the optimization model. Further, two resource allocation strategies are suggested and genetic algorithm is used for optimizing resource utilization and evacuation risk. The results indicate that pooling resources among a cluster of affected areas is most suitable for evacuation. Numerical experiments are conducted to analyze the time trade-offs and the effect of service time variability on the expected evacuation time. The proposed model can serve as an important resource planning and allocation tool for emergency evacuation.

Debt financing and maintenance expenditure: Theory and evidence on government-operated toll roads in China

Transportation infrastructure is the foundation of economic growth, and the existence of high-quality roads is inseparable from their durable maintenance. However, the burden of heavy debt has brought risks to maintenance management and distorted resource allocation. This study builds a two-stage optimal theoretical model under different debt-financing constraints in China, who has the longest expressway mileage of any country in the world. We establish the two principles of “spend-and-debt” and “debt-and-spend” to demonstrate the substitution effect and the complementary effect of debt financing on maintenance, respectively. Furthermore, we use a time-varying differences-in-differences approach to estimate the effect of the financing of tollway bonds on maintenance and further discuss the mechanism. The results provide evidence that there is a significant improvement in the relationship between tollway bonds and maintenance expenditure, mainly due to the reduction of debt costs and the passive propelling of the government’s spending responsibility. Our proposed theoretical and empirical framework sheds new light on transportation infrastructure research. More specifically, the impetus for public expenditure comes from a decrease of the substitution effect, which not only alleviates the burden of debt scale on the public sector but also provides a reference for developing countries to balance infrastructure construction and maintenance.     

An integrative framework for understanding cross-national human resource management practices

Currently, debate in the area of cross-national human resource management (HRM) suggests that both “culture-bound” and “culture-free” factors and variables are important determinants of HRM policies and practices. HRM is presented as being context-specific and it is argued that with the growth of new markets world-wide, and increased levels of competition and globalization of business, there is a strong need for more cross-national HRM studies. However, the literature shows the absence of an integrated framework, which can help to highlight the different role that context-specific facets of HRM practices play. The nature of different determinants in different national and regional settings is rarely analyzed. This paper develops an integrated framework. It delineates the main distinctive facets associated with national factors, contingent variables, and organizational and human resource (HR) strategies and policies, that may be used to evaluate cross-national comparative HRM policies and practices.     

Performance-based resource allocation for higher education institutions in China

How to allocate limited resource to higher education institutions has always been a critical problem with significant social and economic relevance. Researchers and educational administrators have long proposed that resource allocation should be linked to performance. In this paper, we develop a performance-based method for a central planner to allocate research funding to different universities to better stimulate the research output. The method builds on existing works on resource allocation via efficiency analysis. The method takes multiple dimensions of research performance into account, including number of publications, number of patents, and revenue from knowledge transfer. We apply the method to a set of 64 major universities in China based on performance in 2014–2016. The application is particularly pertinent at the moment, since the Chinese government is developing a new funding program called the “double first-class” plan, which features performance-based funding as a central pillar of government funding.

Disaster risk and preference shifts in a New Keynesian model

In RBC models, disaster risk shocks reproduce countercyclical risk premia but generate an increase in consumption along the recession and asset price fall, through their effects on agents’ preferences (Gourio, 2012). This paper offers a solution to this puzzle by developing a New Keynesian model with such a small but time-varying probability of “disaster”. We show that price stickiness, combined with an EIS smaller than unity, restores procyclical consumption and wages, while preserving countercyclical risk premia, in response to disaster risk shocks. The mechanism then provides a rationale for discount factor first- and second-moment (“uncertainty”) shocks.     

Anthropologies of information costs: expanding the neo-institutional view

Neo-institutional economics is credited with acknowledging the role of a “positive information cost” in the formation of economic organizations. However, neo-institutional theory does not explicitly address the problems presented by the loss of information that occurs when organizations change from a face-to-face to electronic channels. An anthropological perspective, in contrast, allows us to explain why this occurs and how organizations can address the dislocations it causes.We argue that Frank Knight’s concept of “uncertainty reduction,” still prominent in current neo-institutional thinking, is insufficient for understanding changes in the firm interface, constitution, and cultural roles resulting from shifts in the cost and nature of information processing. As an extension, we explore paradigms from anthropology, suggesting that changes in the material and social mix of communication are critical in explaining the psychological, cultural and institutional roles that many organizations play, and discuss how these roles are transformed in electronic channels.A five-level framework of information mediation is developed through a case study of an insurance company that has undertaken a dramatic re-engineering of its primary value-adding processes. The framework extends the traditional neo-institutional focus on internal resource allocation towards societal demand and fulfillment of institutional needs. While the new IT/telecom-based processes have substantially improved its cost profile and shifted organizational boundaries, they have also transformed the medium of interaction between the insurer and its customers. As such, the company soon learned that mediating and processing its products through telecom-based channels fundamentally changed the characteristics of its product offering as well as its basis as a social institution.

Workflow process modelling and resource allocation based on polychromatic sets theory

In workflow management, studying the relationship between workflow process activities and resource allocation is one of the interesting research topics. Polychromatic sets theory (PST) is a relatively new mathematical theory which is especially suitable for treating such problems. Based on PST, this paper proposes a framework of workflow process modelling and resource allocation. As the theoretical foundation, polychromatic sets (PS), polychromatic graph (PG) and isolation operation (IO) of the PS are introduced. Special net structure (SNS), a special PG with colourless nodes and concolourous edges, is also introduced, and a new workflow process model and its verification algorithm are presented. Furthermore, a workflow resource model based on the entity of PS is developed. Based on IO of PS, the allocation mechanism that considers workflow process and workflow resource is proposed. Finally, a case study is provided to demonstrate the effectiveness of the above-mentioned theory and method.     

Entrepreneurial performance of early-stage ventures: dynamic resource management for development and growth

Effective allocation of resources for the development and growth of early-stage ventures (ESVs) is a continuous challenge for their equity stakeholders. This paper explores the relevance of intellectual capital (IC) as a critical resource for entrepreneurial performance in ESVs driven by new knowledge development and technological innovation. An interdisciplinary literature review is conducted to examine prior studies on entrepreneurial performance and resource management for ESVs. A conceptual framework is developed using a taxonomy of IC that explains how the underlying network resources enhance the development and growth of ESVs. Utilizing a multiple case study approach, this paper suggests a dynamic process of resource allocation into heterogeneous IC that are optimally coordinated by the founders during an ESV’s development and growth through interaction with external networks. This approach in resource allocation complements the staged entrepreneurial finance and investment strategy for ESVs and their subsequent developments.     

A financial planning model for presidential candidates

The necessity of entering a sequence of interrelated state primaries has forced presidential candidates to be much more deliberate in planning campaign finances. This paper presents a linear programming model for optimal allocation of time and money to each primary in order to maximize the number of delegates won. The model attempts to quantify and exploit the relationships between performance in early primaries and performance in later primaries, which has heretofore been labeled the “snowball effect.” Finally, the model, whose major use would be in overall strategic planning, is illustrated with an example.     

Ramsey Pricing: A Method for Setting Fees in Social Service Organizations

Abstract . In non-profit social services, there is a tendency to avoid setting prices because of the distributional concerns and incompetence on the part of some consumers. Arguments for prices and cash transfers versus in-kind subsidies are reviewed. The appropriateness is examined of “Ramsey pricing” in achieving efficient resource allocation in a zero-profit firm when marginal cost pricing would lead to a profit. A survey of social service agencies in Ontario, Canada, found none was using the principles of “Ramsey pricing” and most were using no fees or prices at all. Some agencies had set prices but then waived them while others set fees equivalent to services provided by nonsocial service agencies. Most view fees as supplemental additions to the budget and consequently do not consider resource allocation. “Ramsey pricing,” it is believed, could be beneficially tried by social service agencies.     

Centralized Resource Allocation Using Data Envelopment Analysis

While conventional DEA models set targets separately for each DMU, in this paper we consider that there is a centralized decision maker (DM) who “owns” or supervises all the operating units. In such intraorganizational scenario the DM has an interest in maximizing the efficiency of individual units at the same time that total input consumption is minimized or total output production is maximized. Two new DEA models are presented for such resource allocation. One type of model seeks radial reductions of the total consumption of every input while the other type seeks separate reductions for each input according to a preference structure. In both cases, total output production is guaranteed not to decrease. The two key features of the proposed models are their simplicity and the fact that both of them project all DMUs onto the efficient frontier. The dual formulation shows that optimizing total input consumption and output production is equivalent to finding weights that maximize the relative efficiency of a virtual DMU with average inputs and outputs. A graphical interpretation as well as numerical results of the proposed models are presented.     

Analysis of the cross-region risk contagion effect in stock market based on volatility spillover networks: Evidence from China

This article uses the stock market regional indexes of 31 provinces (include Province-level municipalities and Minority Autonomous Regions) in mainland China as a sample, and constructs an inter-regional volatility spillover network of China’s stock market based on the GARCH-BEKK model. Through network centrality analysis, Diebold and Yilmaz's spillover index method and block model analysis, we comprehensively analyze the risk contagion effect among different regions in China’s stock market. The empirical results show that: (i) The risk contagion intensity (risk reception intensity) in various regions of China’s stock market has a typical “core-periphery” distribution characteristic due to regions’ different levels of economic development. (ii) There are obvious risk spillover effect in China’s stock market, among which the economically developed regions along the southeastern coast of China, such as Beijing, Shanghai, Zhejiang and Jiangsu, are the main risk transmitters, while the economically undeveloped regions in the Midwest of China, such as Xinjiang, Xizang, Gansu, Nei Menggu and Qinghai are the main risk receivers. (iii) Each region is divided into 4 blocks according to their respective roles in the risk spillover process in China’s stock market. Block 1 that is composed of the economically underdeveloped regions in the Midwest is the “main benefit block”, it acts as a “receiver”. Block 2 that is composed of regions with strong economic growth vitality in the Midwest is a “Bilateral spillover block”, it both plays the role of “receiver” and “transmitter”. Block 3 that is composed of developed regions along the southeast coast, it acts as a “transmitter”; Block 4 that is composed of the relatively fast-growing regions in the Southwest is the “brokers block”, it serves as a “bridge”. The results of this article can provide some reference for investors in financial institutions and decision makers in financial regulators.
