Factors of determining long-term orientation in interfirm relationships

Marketers have witnessed a paradigm shift in which establishing, maintaining, and forging long-term buyer–seller relationships are considered the core of marketing activities. Accordingly, investigating a long-term orientation (LTO) has become a steady research stream in the marketing literature. Building on this on-going research stream, this study confirms that an essential precursor of a manufacturer's LTO is trust that, in turn, is formed by relational norms and satisfaction with supplier performance. Interestingly, however, the seemingly strong trust–LTO path is moderated by both power asymmetry and environmental uncertainty in buyer–seller relationships. The empirical findings suggest that regardless of emerging relationship marketing where buyer and seller are portrayed as parts of a team, power is still in use to control suppliers. In addition, a manufacturer facing uncertainty is less likely to form LTO toward its supplier for fear of losing flexibility in the time- and quality-based competition.     

The underlying mechanism of self-regulatory focus impact on compromise choice

The current research examines the psychological process underlying the differential sensitivity to the compromise effect associated with a distinct self-regulatory focus. In particular, we test two competing hypotheses: one based on the different weights assigned to decision components, and the one that draws on biased perception. This issue is explored via the statistical derivation of decision weights (Study 1), manipulation of the temporal frame of choice (Study 2), and altering the risks associated with decision-making (Study 3). The results of these three studies consistently support the differential weight account: Promotion-focused participants assign greater weight to the desirability (or hedonic value) of the choice outcome, whereas prevention-focused participants place greater weight on the likelihood (or risk) of achieving that outcome. However, perceptions regarding the desirability and the risk of the given choice are similar among those with a distinct self-regulatory focus.     

Is the KOSPI 200 Options Market Efficient? Parametric and Nonparametric Tests of the Martingale Restriction

A number of studies on the S&P 500 index options market claim that the no‐arbitrage assumption cannot be rejected for this market because either the martingale restriction defined in Longstaff (1995) cannot be rejected by the data, or, even when it is rejected, a large proportion of the violation can be explained by market friction factors. The present study singles out the effect of market inefficiency from market friction by testing the martingale restriction for the KOSPI 200 index options market, which is the most liquid and active options market in the world. Not only using the parametric methods adopted in previous studies but also using the nonparametric methods that enable us to avoid the model misspecification problem, we empirically present clear evidence of a violation of the martingale restriction. In addition, in contrast to the S&P 500 options market, regression analyses and robustness tests indicate that market friction factors can explain only a small portion of the percentage differences between option‐implied and market‐observed index prices. Overall, the results do not support the basic no‐arbitrage assumption or the market efficiency in the KOSPI 200 options market.     

ZERO NOMINAL INTEREST RATES,UNEMPLOYMENT, EXCESS RESERVES AND DEFLATION IN A LIQUIDITY TRAP

We present a dynamic monetary model that consistently explains various phenomena such as unemployment, deflation, zero nominal interest rates and excess reserves held by commercial banks. These phenomena were observed during the Great Depression in the USA, the recent long‐run stagnation in Japan and the recent depression triggered by the subprime loan problem in the USA. We show that an excessive liquidity preference leads to a liquidity trap and thereby generates the phenomena.     

Asymmetric Mispricing and Regime‐dependent Dynamics in Futures and Options Markets

We examine regime‐dependent price dynamics and mispricing adjustments within the KOSPI200 spot, futures and options markets through an analysis of data from January 2000 to December 2014. Investors exploit mispricing between derivatives and spot markets only if mispricing is sufficiently large. The futures traders take long, rather than short, positions to adjust for mispricing. Mispricing between spot and options markets is adjusted by trading options and not by trading spots. We find the bidirectional information flows between spot and futures markets when the futures‐implied index is sufficiently larger than the spot index. In contrast, no significant lead–lag relationship between spot and options markets exists. Significant asymmetric transaction costs exist in the spot market and this asymmetry has decreased over time.     

How Rousseau read Hume’s Political Discourses: hints of unexpected agreement in their views of money and luxury

Despite mounting scholarship on the Rousseau–Smith connection, the possibility of overlap between the Humean and Rousseauian views of commercial society has not been explored. This is due to opposing views held by these two thinkers on this issue. However, Rousseau in the Confessions recorded a brief, but shrewd impressions on Hume’s Political Discourses, which he held before meeting Hume. In these comments, Rousseau, unlike his other French contemporaries, noted some republican aspects lurking in Hume’s political and economic essays. Moreover, after his two Discourses, Rousseau composed several other important works in which he revealed his more ‘mature’ economic arguments. Careful readings of these textual clues indicate that, in striking parallel with Hume, Rousseau conducts a thought experiment on the drastic change in the quantity of money and elaborates on the significance of industry and a certain type of luxury. Our purpose here is not to prove that Hume’s Political Discourses directly influenced Rousseau’s later writings, but to measure the extent to which Rousseau could share the Scot’s economic ideas by considering that the former may well have read the latter.     

Investor sentiment,trading behavior and stock returns

This article examines how investor sentiment and trading behaviour affect asset returns. By analysing the unique stock trading dataset of the Korean market, we find that high investor sentiment induces higher stock market returns. We also find that institutional (individual) trades are positively (negatively) associated with stock returns, suggesting the information superiority (inferiority) of institutional (individual) investors. Investor sentiment generally plays a more important role in explaining stock market returns than investor trading behaviour.     

An empirical study on credit card loan delinquency

Following the Basel II convention, consumer credit default is commonly defined as delinquency beyond a period of 90 days. In this study, rather than considering default as a binary variable, we dissect delinquency states further to investigate default behavior in greater detail. As such, we define three states—no delinquency, delinquency and serious delinquency—and estimate the probabilities of the transitions between states using extensive panel data from Korea, covering a wide range of behavioral information. Our findings have several economic implications. First, the factors that affect delinquency risk can differ from those that affect the transition from delinquency to serious delinquency. Second, the recent increase in the number of seriously delinquent accounts can be attributed to changes in the borrower age distribution. Third, macroeconomic conditions, especially differences in gross domestic product and consumption growth, have led to the recent increase in delinquent accounts. Fourth, the debt-to-income (DTI) ratio has a profound effect on transitions between delinquency states and thus affects both recovery and delinquency. Furthermore, this result is robust to controls for demographic and macroeconomic factors.     

Economic assumptions and choice of functional forms: comparison of top down and bottom up approaches

Two alternative model building approaches are analyzed and compared. The general to specific modeling (top down approach) starts with a general model and subjects it to a sequence of restrictions to determine an acceptable specific model. This approach can start with a series expansion and the concavity or homotheticity conditions can be imposed to modify it into a cost or a production function. The simple to general modeling (bottom up approach) starts with a well known simple model and extends it until a complete system is formed. This approach can start with a Cobb-Douglas function (which satisfies the concavity and homogeneity conditions) and extends it to include the desired complexity. Relative advantages and disadvantages of the two approaches are discussed and tabulated. The electricity generation data is applied to compare the performance of these two approaches.

How agglomeration affects alliance governance and innovation performance: The role of cluster size

We investigate how the size of the geographic cluster in which a firm is located influences its governance choice between equity and non-equity alliances and subsequent innovation performance. We argue that firms located in larger clusters tend to form non-equity alliances rather than equity alliances because the communication and control benefits of cluster membership, which increase with cluster size, reduce in-cluster firms' need to form equity alliances. We also claim that the effect of this preferential use of non-equity alliances on innovation becomes stronger when firms are located in larger clusters. Our arguments are supported by a panel analysis of alliances formed by US-listed semiconductor firms.
