Duality Theory and Long–Period Price Systems

This paper concerns duality between long–period price systems in Sraffian models of production and the technologies of the various industries. We present a ‘principle of duality between prices and technique’ referred to a system of production, due to Bidard and Salvadori, and compare it with the usual textbook duality between cost and production functions, referred to firms/industries. We argue that the principle of duality for the system of production can be obtained, industry by industry, on the basis of the usual duality theory and that, in so doing, both ‘dualities’ are given a formulation more appropriate to firms/industries in long–period equilibrium.     

The Duality of Crony Corruption in Economic Transition: Toward an Integrated Framework

In order to shed light on the issue of crony corruption in the context of economic transition, I focus on the puzzle of China’s unique experience of economic transition characterized by the duality forms and effects of crony corruption underlying local corporatism in a dual-track (i.e., market and political tracks) transition. I argue that the duality of local corporatism derives from the duality of crony corruption. First, the early form of local corporatism as state-business public alliance is embedded in informal crony corruption as positive for the purpose of wealth growth in the initial phase of economic transition with public and private interests aligned as compatible. Second, the later form of local corporatism as official-manager private collusion is embedded in quasi-formal crony corruption as negative for the purpose of wealth transfer in the later phase with public and private interests in conflict as incompatible. The duality of crony corruption in the two phases of economic transition is caused by the interplay between formal and informal factors and between economic and political factors. My contribution is twofold. First, I explain China’s transition in terms of crony corruption underlying local corporatism. Second, I develop an integrated framework of crony corruption concerning its content, process, antecedent and consequence.     

Linear Programming and the von Neumann Model

The formal similarity between von Neumann's theorem on maximal growth and (a weak form of) the fundamental theorem of linear programming is striking. The parallelism is explained by considering a simple economy for which the two problems are identical.     

CEO Duality and Firm Performance: Does Economic Policy Uncertainty Mediate the Relation?

Exploiting two exogenous shocks, we examine the relation between CEO–Chairman duality and firm performance. We report evidence that CEO duality benefits a firm when economic policy uncertainty is high. This implies that CEO–‐Chairman duality is an advantageous governance mechanism for coping with economic policy uncertainty. We show that the Sarbanes‐Oxley Act reduced firm performance if a firm had separate leadership in 2001. However, this negative effect was mitigated if a firm had combined leadership in 2001. The results suggest that CEO duality is complementary to board independence and that the value of CEO duality is contingent on a firm’s environment.     

On Determinants of Japan's Foreign Direct Investment in Eastern Europe

Summary

The paper takes issue with some untested but often repeated assertions that Japanese FDI positions in Eastern Europe are weak. Japan's economic relations with Eastern Europe, including FDI, should be understood in the context of Japan's global economic relations. Therefore, it might not be appropriate to approach the question armed with absolute FDI numbers only. So, the author proceeds to empirically test some of these assertions by calculating directional trade ratios and directional FDI ratios! As a result of his approach, he claims that Japan's FDI position in Poland is not significantly weaker compared to its trade position or to other advanced countries' positions. The paper also suggests that, although Japan's FDI in Poland has been undoubtedly stagnant, the larger problem is that the Polish FDI environment is still problematic due mainly to repayment risks and rather low levels of real per capita income.     

Non-uniqueness Through Duality in the Von Neumann Growth Models

Duality can be viewed as the soul of each von Neumann growth model. This is not at all surprising because von Neumann (1955), a mathematical genius, extensively studied quantum mechanics which involves a “dual nature” (electromagnetic waves and discrete corpuscules or light quanta). This may have had some influence on developing his own economic duality concept. The main object of this paper is to restore the spirit of economic duality in the investigations of the multiple von Neumann equilibria. By means of the (ir)reducibility taxonomy in Móczár (1995) the author transforms the primal canonical decomposition given by Bromek (1974) in the von Neumann growth model into the synergistic primal and dual canonical decomposition. This enables us to obtain all the information about the steadily maintainable states of growth sustained by the compatible price-constellations at each distinct expansion factor.

Organizations as Human Communities and Internal Markets: Searching for Duality

Business firms have been explained as internal markets or as communities. To be sustainable, however, they need to reconcile these two constituting elements that have mainly been touted as opposite and part of a dualistic relationship. We suggest that organizations may, in alternative, view market and community as part of a duality, interdependent and mutually constituting processes that may not only contradict each other but also enable one another. The implications of a duality view for business ethics, which articulates market and community elements in a fruitful, mutually enabling relationship, are considered, and duality is presented as a way of transcending what is commonly viewed as opposition, moving organizations both in the direction of humane and competitive finalities.     

FORMALIZING WIESER's THEORY OF DISTRIBUTION: CONSISTENT IMPUTATION IN ALTERNATIVE THEORETICAL PERSPECTIVES

Wieser's theory of value and distribution has been formalized and interpreted mainly in the framework of efficient allocation of scarce resources. To this end, the mathematical techniques of linear programming have been used by such authors as Samuelson and Uzawa. This paper presents briefly what may be called the Knight–Samuelson–Uzawa formalization and supplements it with different proposed formalizations of some further aspects consistently developed in Wieser's works. The formalization that we propose concerns Wieser's theory of interest and his theory of value for ‘cost goods’. It is argued that in such cases the produced means of production, and not the endowments of scarce resources, are at the centre of Wieser's analysis. It is shown that some appropriately specified models in the Sraffa–von Neumann–Leontief tradition can very usefully be employed in order to strengthen Wieser's intuitive arguments and give them a sound analytical structure.     

Optimal bank asset and liability management with financial futures

This paper presents a model for optimal bank asset and liability management with financial futures. This model is a multiperiod linear programming model based on Markowitz portfolio theory. Given the bank's initial position, its economic forecasts, and the constraints under which it operates, the model can help a bank's senior executives determine the current and expected future balance sheet composition and financial futures position which will minimize the bank's operating risks and which will meet the bank's expected profits goal with the minimum possible profits risk. By parametrically varying the expected profits goal, the model will generate the set of risk-return efficient decisions. Bankers need then examine only the set of efficient decisions to choose their optimal solution. A simplified example is used to illustrate the application of our model and to demonstrate that banks that use financial futures in asset and liability management can obtain better results than banks that do not use financial futures.     

Hong Kong after 1997: The question of sovereignty

Ever since British-Chinese negotiations over the return of Hong Kong began in 1982, there has been a dialogue of the deaf about Hong Kong's future, Overholt provides a thorough overview of the historical, political economic, social and legal issues regarding Hong Kong's transition and of China's self-interest in Hong Kong's major functions as an airlock, entrepot, financial center, regional headquarters and manufacturer. Through his careful discussion of the foreseeable problems, Overholt reaches the conclusion that hong Kong is “useful pretty much the way it is” to China and doesn't see China disturbing the balance.     

Preference robust distortion risk measure and its application

Distortion risk measure (DRM) plays a crucial role in management science and finance particularly actuarial science. Various DRMs have been introduced but little is discussed on which DRM at hand should be chosen to address a decision maker's (DM's) risk preference. This paper aims to fill out the gap. Specifically, we consider a situation where the true distortion function is unknown either because it is difficult to identify/elicit and/or because the DM's risk preference is ambiguous. We introduce a preference robust distortion risk measure (PRDRM), which is based on the worst-case distortion function from an ambiguity set of distortion functions to mitigate the impact arising from the ambiguity. The ambiguity set is constructed under well-known general principles such as concavity and inverse S-shapedness of distortion functions (overweighting on events from impossible to possible or possible to certainty and underweighting on those from possible to more possible) as well as new user-specific information such as sensitivity to tail losses, confidence intervals to some lotteries, and preferences to certain lotteries over others. To calculate the proposed PRDRM, we use the convex and/or concave envelope of a set of points to characterize the curvature of the distortion function and derive a tractable reformulation of the PRDRM when the underlying random loss is discretely distributed. Moreover, we show that the worst-case distortion function is a nondecreasing piecewise linear function and can be determined by solving a linear programming problem. Finally, we apply the proposed PRDRM to a risk capital allocation problem and carry out some numerical tests to examine the efficiency of the PRDRM model.     

Expanding near the home base or venture far? The influence of home country state on the economic distance of foreign direct investments

The extent of the economic distance between a firm's home origin and its foreign direct investment (FDI) is an important strategic decision for the investing firm. This study fills an important knowledge gap by investigating the home institutional antecedents of FDI economic distance. Drawing insights from comparative institutionalism, we argue that home-country states vary in both their power to coordinate the economy and the external and internal channels through which they exercise that power. These variations have implications on a firm's motivation and capability to escape external dependencies on the home-country state by investing in economically distant foreign locations. Empirically, using a dataset of 891 new international entrants from 2004 to 2011, we found support for our hypotheses that home-country state power is positively associated with FDI economic distance, and that the influence of the home-country state is contingent on the state's governance quality and its ownership in firms.     

Regional Diversity and Sources of Economic Growth in China

Regional diversity in the process of economic growth is the major concern in this paper. We will try to identify its sources for growth and to specify production functions in each province by estimating translog production function. This paper clarifies the following four facts: First, capital accumulation was a major source for growth in the earlier stage of the Chinese economy, especially in the eastern coastal region. Unexpectedly, capital accumulation is losing its ground over the years. Second, the employment structure of the economy in the eastern region has changed significantly and the shares of workers in the secondary and tertiary industries increased until 1992. Since 1992, these figures have not changed significantly despite China's continuous economic high growth. Third, four distinguishable regional growth patterns have contributed to China's economic growth. Finally, production technologies in each province vary both in the direction of factor intensity and in the elasticity of substitution between inputs.     

Measuring Effects of Trade Policy Distortions: How Far Have We Come?

After a brief review of the literature to the early 1970s, this paper assesses the contributions by economists during the past three decades to measuring the distortionary effects of trade policies. It does not pretend to be a comprehensive survey, but draws on selections from the literature that give a sense of the distance the profession has travelled from a trade policy practitioner's viewpoint since Corden's first paper on the subject in 1957. Phenomenal though that progress has been, there is ample room for further improvement in computing the economic (and other) effects of trade‐related policies and their reform. The paper concludes with suggestions of where the priorities should be in global modelling of trade policy reform, as the world moves into the next round of multilateral trade negotiations.

A MODEL OF THE MATURITY PROFILE OF THE BALANCE SHEET (1)

In this paper, the expected return-variance of return hypothesis of investment behavior is applied to the problem ot the wealth-holder's choice of the maturity distributions of his assets and liabilities. It is assumed that the only asset forms available to the wealth-holder are bonds homogeneous in all respects except: the dates on which they promise with certainty to pay their face values plus interest in a single lump sum. Bonds are assumed to be available from a continuous spectrm of maturities in infinitely divisible denominations. The wealth-holder is assuined, in addition, to make risky forecasts of the future level of interest rates. Under these assumptions, the wealth-holder's networth is a random variable with given mean and variance. Expected net-worth and its variance are shown to be functions of a set of moments describing the distributions by maturity date of the wealth-holder assets and liabilities, i. e., the wealth-holder views the maturity distributions of his assets and liabilities as statistical frequency functions capable of being described by a set of statistical moments. These moments are then treated as the wealth-holder's decision variables to be adjusted to maximize a utility function over expected net-worth and its variance. Optima 1 values of these moments then describe the optimal maturity profile of the wealth-holder's balance sheet.     

环境约束下的中国省区经济增长源泉的收敛机制分析

在考虑环境因素的条件下,利用序列DEA、方向性距离函数以及经济增长的四元分解模型,将中国省区的经济增长分解为绿色技术进步、绿色技术效率改善、资本深化和人力资本积累4个部分。在此基础上,利用动态空间面板数据模型分析各增长源泉对中国省际经济差距的影响及作用机制。研究发现:绿色对中国省际经济差距的影响要大于各种投入因素,在绿色的构成中,尽管绿色技术效率存在恶化趋势,但它却是造成中国省际经济差距扩大的主要原因;在投入因素中,资本深化对中国省际经济差距的扩大有较大影响,而人力资本的影响并不明显。最后,从技术、环境和投入等方面提出缩小中国省际经济差距,实现省区经济、资源、环境协调发展的相关政策建议。     

Growth Intentions and Board Composition in High‐Growth Firms

This paper examines the influence of board composition on growth intentions of high‐growth firms. We hypothesize that gender diversity and a high proportion of independent directors on the board will reduce a firm's growth intentions, whereas founder duality will increase a firm's growth intentions. Using survey data from 773 high‐growth Norwegian firms, we find that gender diversity has a negative effect on growth intentions. A high proportion of independent directors do not facilitate further growth in high‐growth firms. Furthermore, our results indicate that the founder's presence in the decision‐making group increases a firm's growth intentions.     

Trading under the proof-of-stake protocol – A continuous-time control approach

We develop a continuous-time control approach to optimal trading in a Proof-of-Stake (PoS) blockchain, formulated as a consumption-investment problem that aims to strike the optimal balance between a participant's (or agent's) utility from holding/trading stakes and utility from consumption. We present solutions via dynamic programming and the Hamilton–Jacobi–Bellman (HJB) equations. When the utility functions are linear or convex, we derive close-form solutions and show that the bang-bang strategy is optimal (i.e., always buy or sell at full capacity). Furthermore, we bring out the explicit connection between the rate of return in trading/holding stakes and the participant's risk-adjusted valuation of the stakes. In particular, we show when a participant is risk-neutral or risk-seeking, corresponding to the risk-adjusted valuation being a martingale or a sub-martingale, the optimal strategy must be to either buy all the time, sell all the time, or first buy then sell, and with both buying and selling executed at full capacity. We also propose a risk-control version of the consumption-investment problem; and for a special case, the “stake-parity” problem, we show a mean-reverting strategy is optimal.
