The lens used by the courts and much of the antitrust literature on predatory selling and/or buying is based on partial equilibrium methodology. We demonstrate that such methodology is unreliable for assessments of predatory monopoly or monopsony conduct. In contrast to the typical two-stage dynamic analysis involving a predation period followed by a recoupment period, we advance a general equilibrium analysis that demonstrates the critical role of related industries and markets. Substitutability versus complementarity of both inputs and outputs is critical. With either monopolistic or monopsonistic market power (but not both), neither predatory overselling nor predatory overbuying is profitably sustainable. Two-stage predation/recoupment is profitable only with irreversibility in production and cost functions, unlike typical estimated forms from the production economic literature. However, when the market structure admits both monopolistic and monopsonistic behavior, predatory overbuying can be profitably sustainable while overselling cannot. Useful distinctions are drawn between contract versus non-contract markets for input markets.

This paper aims to study the preferences of the supply chain (SC) members on various power structures under demand information asymmetry considering competing retailers.

A two-level SC with one manufacturer and two retailers is designed. The retailers are in Bertrand competition. The manufacturer who holds the confidential demand information chooses the appropriate information sharing (IS) format. Three IS formats are provided, i.e. no IS (the manufacturer never shares with the retailers), partial IS (the manufacturer shares with one retailer), full IS (the manufacturer shares with all retailers). In addition, the authors model two power structures based on the decision sequences in the SC, i.e. retailers or manufacturer-dominant SC. The authors characterize the equilibrium solutions and payoffs and then investigate the members’ preferences for IS formats.

It is shown that in retailers (manufacturer)-dominant SC, the retailers prefer full (no) IS, but the manufacturer prefers no (full) IS. Moreover, the authors analyze the members’ preferences on power structures under demand information asymmetry, which has a relationship with the degrees of demand uncertainty and competition intensity.

The analysis regarding the preferences of the SC members on power structure under demand information asymmetry provides valuable managerial insights to enhance cooperation and achieve a win-win result.

Regional comprehensive economic partnership (RCEP) is understood as the world's largest trading bloc given its contribution to the world output (30%). The mega trade bloc brings together 15 countries of East Asia, Southeast Asia and Oceania to eliminate tariff and non-tariff barriers in goods and services trade. The study suggests the importance of sector specific reforms for Malaysia to strengthen domestic capability.

The analytical framework constructs upon the partial equilibrium analysis and uses WITS SMART simulations.

The study finds that Malaysia's elimination of tariffs under the RCEP will cause a surge in imports from developed member countries of RCEP like Australia, South Korea and Japan. The study also finds a trade diversion in countries such as India. The empirical results establishes that RCEP would further strengthen intra-ASEAN trade.

The study explores select sectors of the manufacturing industry in Malaysia.

The implementation of RCEP would impact the manufacturing sector immensely, especially in sectors like electrical machinery and equipment and inorganic chemicals, which are two of the major trading commodities of the Malaysian economy.

Any trade agreement has a larger impact on the society. It may raise income, boost the consumer preferences and create or erode consumer welfare. The study reports the consumer welfare effect of the implementation of RCEP in Malaysia.

The study is the first attempt to do a partial equilibrium analysis for the electrical machinery and equipment sector and inorganic chemicals sector of Malaysia using both aggregated and disaggregated data at HS two-digit and HS six-digit level.

When a pure titanium component is fabricated in a selective laser melting (SLM) process using titanium powder, the oxygen concentration of the SLM sample increases compared to the initial powder. The purpose of this paper is to study the reason for increasing oxygen concentration after SLM.

To understand this phenomenon, the authors analyzed the oxidation behavior during the SLM process thermodynamically.

Based on the laser parameters used in this study, the temperature of the Ti melt during the SLM process was expected to rise to 2,150°C. Based on the thermodynamic analysis, the equilibrium oxygen partial pressure for oxidation was 2.32 × 10⁻¹⁹ atm at 2,150°C when the dissolved oxygen concentration in the titanium is 0.2 wt.%. However, the oxygen partial pressure inside the SLM chamber was 1 × 10⁻³ atm, which is much higher than the equilibrium oxygen partial pressure. Therefore, oxidation occurred during the SLM process, and the oxygen concentration of the SLM sample increased compared to the initial powder.

Most studies on fabricating Ti components using additive manufacturing (AM) have been focused on how the changes in the microstructures and mechanical properties depend on the process parameters. However, there are a few studies that analyzed the oxygen concentration change of Ti during the AM process and its causes. In this study, the authors analyzed the oxidation behavior during the SLM process thermodynamically.

The purpose of this paper is to build a unified model of human information behavior (HIB) for integrating classical constructs and reformulating the structure of HIB theory.

This paper employs equilibrium perspective from partial equilibrium theory to conceptualization and deduction, starting from four basic assumptions.

This paper develops two models to incorporate previous HIB research approaches into an equilibrium-analysis-oriented information supply-demand (ISD) framework: first, the immediate-task/problem-based and everyday life information-seeking (ELIS)-sense-making approaches are incorporated into the short-term ISD model; second, the knowledge-construction-oriented and ability-based HIB research approaches are elaborated by the long-term ISD model. Relations among HIB theories are illustrated via the method of graphical reasoning. Moreover, these two models jointly reveal the connection between information seeking in immediate problematic situations and long-term ability improvement.

The equilibrium framework enables future research to explore HIB from three perspectives: stages: group the classical concepts (e.g. anomalous state of knowledge, uncertainty) into different stages (i.e. start state, process, goal state) and see how they interact with each other within and across different stages; forces: explore information behaviors and information-related abilities as information supply and demand forces, and see how different forces influence each other and jointly motivate people to pursue the equilibriums between outside world and mental model; and short term and long term: study the connections between short-term information seeking and long-term ability improvement at both theoretical and empirical levels.

The purpose of this paper is to study the optimal coverage limit in a model of deposit insurance with capital requirements and risk sensitive premia to prevent moral hazard.

The theoretical model has incorporated capital requirements, risk‐sensitive premium, and partial deposit insurance in a partial equilibrium model. The model discusses the interaction among risk‐taking banks, ex‐ante heterogeneous depositors, and a deposit insurer.

First, the paper shows that optimal coverage encourages depositors' monitoring and withdrawals. Partial deposit insurance improves social welfare. Second, risk‐sensitive premia and market discipline are essential to reduce bank risk taking behavior. Third, adjustment between level of coverage and the premium guarantees long term liquidity of the deposit insurance funds and makes banks better off. Fourth, numerical findings are consistent with the empirical evidence that shows differences in coverage between countries.

Timing and frequency of adjustments to coverage limits and the implementation of co‐insurance have been beyond the scope of this study but those implications are worth further investigation.

In the current crisis, banking regulations combined with poor management and supervision have been responsible for banks' improper leverages, lending and securitization. A bank failure could easily turn into a crisis when the financial institution is overly exposed to credit risks and when the government is least equipped to deal with those risks. Thus, the study of the partial deposit insurance is important in achieving stability in the banking sector.

This theoretical paper aims to illustrate that tourism economies differ substantially with respect to market conditions, such as demand elasticity and industrial structure, which have a clear effect on the distribution of the tax burden.

This paper has used partial and general equilibrium frameworks to study the effects of a production tax on the overall welfare of a tourism economy. The two frameworks are linked via the relative price of tourism based on the assumption that it is influenced by a typical tourism economy that is able to enjoy a certain degree of market power in its tourism exports.

We have discovered that the division of the tax burden is significantly affected by local market conditions, such as demand elasticity and industrial structure. Generally, tourism economies differ with respect to those characteristics, which can be crucial in determining the success of a tourism tax. This line of research has enabled us to determine why different tourism tax rates have been adopted in various markets and to provide a justification for government selection of a particular tax in a given market. The rational criterion for tax choices is to maximize the likelihood of enhancing welfare or to minimize the risk of reducing efficiency.

This paper argues that those conditions are crucial to determining the success or failure of a tourism tax and may thus be able to explain why each tourism economy has adopted a different tax.

The purpose of this contribution is the investigation and the assessment of François Perroux’s book – Unités Actives et Mathématiques Nouvelles – Révision de la théorie de l’équilibre économique général (Perroux, 1975a) – in connection with the research program he initiated before and during the Second World War. Concerning the analytical relevance of this book there is no consensus. According to some economists it has to be considered as the masterpiece of Perroux’s intellectual project which provides an alternative approach to the usual theory of general economic equilibrium (GEE). Others think that today the book is almost entirely forgotten and it does not help really to improve Perroux’s general research project. We try to set here our own view combining two ways of proceeding in the investigation about the relevance of the book. The first one develops an analysis of Unités Actives as dispassionate as possible, avoiding taking into account the personality as well as the social and political views of François Perroux. The second favors a retrospective approach relating the 1975 book to the previous contributions of the author. The first three sections of our contribution are dedicated to Perroux’s contributions written before his attempt to “revise” the usual version of the GEE theory. The five following sections are devoted to the direct contents of the “revision” of this theory and tries to propose a global assessment of it.
