Descending price multi-item auctions

We propose a simultaneous descending price auction mechanism to sell multiple heterogeneous items, each owned by a distinct seller, to a number of buyers. Each buyer has known private valuations on items, and wants at most one item. We show that if the sellers follow a descending price offer procedure and the buyers follow a greedy strategy for accepting the offers, the auction results in a nearly efficient allocation, and terminates close to a competitive equilibrium price vector. The descending price offer strategy of the sellers is close to a Nash equilibrium. However, we show that the buyers are better off waiting in our auction. There is a maximum limit (corresponding to the minimum competitive equilibrium price vector) till which they can wait without running into the risk of not winning any item. If the buyers wait within this limit, the prices can be brought arbitrarily close to a uniquely defined competitive equilibrium price vector.     

Evaluating inflation targeting as a monetary policy objective for India

This study formulates a small open economy model for India with exchange rate as a prominent channel of monetary policy. The model is estimated using the Instrumental Variable-Generalized Methods of Moments (IV-GMM) estimator and evaluated through simulations. This study compares different cases of domestic and CPI inflation targeting, strict and flexible inflation targeting, and simple Taylor type rules. The analysis highlights the unsuitability of simple Taylor-type monetary rules in stabilizing the Indian economy and suggests that discretionary optimization works better in stabilizing this economy. There seems to be a trade-off between output gap stabilization and exchange rate stabilization in flexible domestic inflation targeting and CPI inflation targeting respectively. However, flexible domestic inflation targeting seems a better alternative from an overall macro stabilization perspective in India where financial markets are still not sufficiently integrated to ensure quick transmission of interest rate impulses and existence of rigidities in the economy.     

Frequent acquirers and management compensation

We find positive contemporaneous, short-, and long-run effects of an increase in the acquisition rate on management compensation. A positive bidirectional causality exists between acquisition frequency and management compensation. A higher firm value is likely to associate with higher acquisition frequency. Acquisition rate has a positive impact on the market share. Acquirers with lower market share are more likely to become frequent acquirers. A causal order follows from lower market share to higher acquisition frequency to higher firm value to higher management compensation. The impact of acquisition frequency on management compensation is higher for value-enhancing acquirers relative to value-destroying acquirers.     

Interval-Valued Intuitionistic Fuzzy WASPAS Method: Application in Reservoir Flood Control Management Policy

Interval-valued intuitionistic fuzzy sets (IVIFSs) are very flexible tool to cope with the uncertainty arises in multi-criteria decision making (MCDM) problems. In recent times, MCDM problems with interval-valued intuitionistic fuzzy information have achieved more attention from researchers in different areas and consequently, several MCDM methods have been extended for IVIFSs. In this paper, a novel approach based on WASPAS method is developed under IVIFSs. The developed method is based on the operators of IVIFSs, some amendments in the classical WASPAS method and a new process for calculation of criteria and decision experts’ weights. In process for calculating weights, new procedures is propoesd to compute the decision experts’ weights and criteria weights based on interval-valued intuitionistic fuzzy information measures (entropy, divergence and similarity measures) to achieve more realistic weights. Innovative information measures are developed based on the exponential function for IVIFSs to determine the weights of the criteria and decision experts. Since the uncertainty is an unavoidable feature of MCDM problems, the developed method can be a constructive tool for decision-making in an uncertain environment. Further, an uncertain decision making problem of reservoir flood control management policy is implemented with interval-valued intuitionistic fuzzy information, which reveals the effectiveness and reliability of the proposed IVIF-WASPAS method. To validate the result, comparative analysis with existing methods and sensitivity analysis are presented under interval-valued intuitionistic fuzzy environment.     

Estimating Technical Efficiency and Production Risk under Contract Farming: A Bayesian Estimation and Stochastic Dominance Methodology

We investigate production risk, technical efficiency and risk attitudes amongst contract and independent farmers. We use a Bayesian parametric approach and stochastic dominance quantile regression methods to compare technical efficiency and risk attitude of smallholders in Nepal. Using farm‐level data, we find that contract farmers appear to show lower inefficiency and lower production risk. Additionally, contract and independent farmers can increase output by reducing the scale of operation. Regardless of the commodity produced and farming arrangement (contract or independent production), we find that labour, land and other inputs are risk‐augmenting, while the role of capital is mixed. We find a second order stochastic dominance (SSD) for lentils, and first order stochastic dominance (FSD) for tomatoes, ginger and HYV paddy seed commodities. Finally, contract farmers are more risk averse than independent farmers, regardless of the commodity produced.     

Financial development and top income shares in OECD countries

We examine the causal impact of financial development (FD) on top income shares for a panel of 14 OECD countries—five Anglo‐Saxon countries, eight continental European countries, and Japan—over a 110‐year period. In our main General Method of Moments estimates, we find that a 1‐percentage‐point change in FD increases the top 1% income share by 0.2%. In distribution terms, a 1‐SD incr=ease in FD increases the top 1% income share by around 0.4 of an SD. The effects are robust to various measures of top income shares and FD and alternative estimation techniques, including nonparametric estimation. FD is typically viewed in positive terms in that it makes it easier to access credit and facilitates economic growth. Our results are important because they contribute to understanding of the potential negative effects of FD.     

Conditional convergence in US disaggregated petroleum consumption at the sector level

We test for convergence in disaggregated petroleum consumption at the sector level for the United States using the recently proposed GARCH unit root test, suitable for high frequency data. We find evidence of convergence for just over half of the series, including total petroleum consumption in each sector and approximately three quarters of the disaggregated petroleum consumption series in transportation.     

Ownership Structure and Firm Performance: Evidence from Vietnamese Listed Firms

We examine the effect of ownership structure on firm performance, for firms listed on Vietnamese stock exchanges, using 2744 firm‐year observations over the period from 2007 to 2012. We find a non‐linear relationship between ownership structure and firm performance. State ownership has a convex relationship with firm performance. This paper finds that firm performance increases beyond 28.67 percent level of state ownership. Foreign ownership has a concave relationship with firm performance. We find that firm performance increases with an increase of foreign ownership up to a level of 43 percent and then decreases. Policy makers should encourage foreign ownership and widely dispersed state ownership in firms, which can help improve firm performance.     

Corporation Diversification and Firm Performance: Evidence from Vietnamese Listed Firms

We examine the effect of corporate diversification on the performance of firms listed on the Vietnamese stock exchanges, using 2744 firm year observations over the period from 2007 to 2012. We find that corporate diversification has a negative impact on firm performance. Our results are robust to various econometric estimation techniques including fixed effect, instrumental fixed effect, Heckman selection model and system generalised method of moments. In the Vietnamese context, the lack of an efficient corporate governance system may encourage firms to follow corporate diversification strategies, thus impairing their performance.
