Volatility Spillover Effects in Interregional Equity Markets: Empirical Evidence from Brazil and Turkey

We investigate volatility spillovers between two stock markets: Turkey and Brazil. Using a misspecification-robust causality-in-variance test, we find evidence supporting volatility spillovers from the São Paulo Stock Exchange to the Istanbul Stock Exchange. Moreover, the results imply that financial crises may change the nature of volatility spillovers between the two markets by adding an additional channel of volatility transmission from Turkey to Brazil.     

Who Transfers Credit Risk? Determinants of the Use of Credit Derivatives by Large US Banks

Abstract

Credit derivatives enable banks to transfer selected credit risks to third parties. An empirical model is developed for the motivation for bank participation in credit derivative markets and, conditional on participation, the factors that determine the volume of business transacted. Participation appears to be closely related to bank size, but there is only limited evidence that entry barriers related to franchise value or past experience in dealing in derivatives are important. There is evidence that banks use credit derivatives as part of their overall risk management strategy. However, the use of credit derivatives does not appear to be influenced by the extent of managerial share ownership.     

Merits of Task Advice during New Product Development: Network Centrality Antecedents and New Product Outcomes of Knowledge Richness and Knowledge Quality

Utilizing new product development (NPD) teams to accomplish complex tasks in firms has been an emergent issue in many industries throughout the last couple of decades. Despite numerous studies, formation and efficient management of NPD teams is still a developing research domain. Using the knowledge‐based view of the firm and social network theories complementarily, this paper contributes to literature by examining the intrafirm social relational structures of NPD teams. Focusing specifically on the network centrality of the NPD teams, this paper argues that network centrality types of closeness, betweenness, and degree centralities influence the quality and richness characteristics of knowledge received through task advice seeking. Subsequently, the knowledge gained with these characteristics enhances product innovativeness and new product success. Consequently, the second contribution of this paper is to conceptualize the effect of the task advice‐seeking activities of NPD teams on NPD outcomes. The paper concludes with a discussion of the empirical testing of the proposed model, including suggestions for focal construct operationalizations as well as other future research directions.     

Topological Properties of the International Trade Network Using Modified Measures

This article modifies several social network analysis measures to get a more accurate picture of the topology of international trade. Modifications improve estimations of actual network relationships by avoiding leaving out any trade links, considering directionality of trade, recognizing product-level networks and differences in relative importance of countries, products, and links by weighing the measures. These methods are adopted to modify measures of reciprocity, multiplexity, clustering, degree, betweenness, and closeness centrality. Changes in the trade network over the most recent dozen years are analyzed and several observations are made about trends.

Nonlinearity and structural stability in the Phillips curve: Evidence from Turkey

In this paper, we investigate possible nonlinearities in the inflation–output relationship in Turkey for the 1980–2008 period. We first estimate a linear bivariate model for the inflation rate and output gap, and test for linearity of the estimated model against nonlinear alternatives. Linearity test results suggest that the relationship between the inflation rate and output gap is highly nonlinear. We estimate a bivariate time-varying smooth transition regression model, and compute dynamic effects of one variable on the other by generalized impulse response functions. Computed impulse response functions indicate that inflation–output relationship in Turkey during the analyzed period was regime dependent and varied considerably across time.     

The role of endowments,technology and size in international trade: new evidence from product-level data

Using product-level trade data, we empirically investigate the export patterns of more than 150 countries in their exports to the USA, Brazil, India, and Japan. We document strong evidence that exporters specialize according to their relative factor endowments, technology, and economic size. More developed, capital abundant countries are found to export products of higher unit values and a wider range of products to developed, emerging and developing markets. More developed, economically larger, and technologically advanced countries are also the major exporters of new products, spanning a wide range of product categories with high unit values. Our findings provide important insights into the macro phenomenon that a large proportion of the global trade takes place among developed economies, and that the latter are also major exporters to developing markets.     

The demand for agricultural land and strategic bidding in auctions

A unique feature of land auctions is that the same land is auctioned twice; first the land is broken into tracts and each tract is auctioned individually. Then, the tracts are reassembled and auctioned as a whole parcel. After the two auctions are completed, the seller chooses the one that generates a higher revenue. The main purpose of this paper is to provide an explanation of why such an auction design is employed to sell farmland. We also show that this feature of land auctions leads to interesting interaction among the bidding strategies of the players in each of the two auction stages.
