Antecedents and consequences of chronic impulsive buying: Can impulsive buying be understood as dysfunctional self‐regulation? 下载免费PDF全文
Researchers reach different conclusions about the functional or dysfunctional nature of impulsive buying behavior. While many note the use of impulsive buying as a form of mood regulation, there is disagreement about whether this is functional or dysfunctional and the extent to which it causes financial harm. This paper draws on data from a U.K. national survey sample (N = 109,472) to contribute to these debates. Study results suggest that impulsive buying is more common for those who have most need to regulate mood and who have the least effective emotion regulation strategies. This suggests that impulsive buying may be understood as a failure of self‐regulation in relation to long‐term goals and as a strategy for mood regulation. Contrary to some prior claims in the retail management and marketing research literature, the study shows higher levels of impulsive buying to be associated with more adverse financial outcomes (which are not confined to the most extreme manifestations of the trait). While ineffective emotion regulation is associated with higher propensity to buy impulsively, the findings also suggest that effective emotion regulation may to some extent mitigate the adverse consequences of the propensity to buy impulsively. The implications for ethical management, research, and policy are considered. 相似文献

We propose a computationally efficient and statistically principled method for kernel smoothing of point pattern data on a linear network. The point locations, and the network itself, are convolved with a two‐dimensional kernel and then combined into an intensity function on the network. This can be computed rapidly using the fast Fourier transform, even on large networks and for large bandwidths, and is robust against errors in network geometry. The estimator is consistent, and its statistical efficiency is only slightly suboptimal. We discuss bias, variance, asymptotics, bandwidth selection, variance estimation, relative risk estimation and adaptive smoothing. The methods are used to analyse spatially varying frequency of traffic accidents in Western Australia and the relative risk of different types of traffic accidents in Medellín, Colombia. 相似文献

The paper investigates the information content of speculative pressure across futures classes. Long-short portfolios of futures contracts sorted by speculative pressure capture a significant premium in commodity, currency, and equity markets but not in fixed income markets. Exposure to commodity, currency, and equity index futures’ speculative pressure is priced in the broad cross-section after controlling for momentum, carry, global liquidity, and volatility risks. The findings are confirmed by robustness tests using alternative speculative pressure signals, portfolio construction techniques, and subperiods interalia. We argue that there is an efficient hedgers-speculators risk transfer in commodity, currency, and equity index futures markets. 相似文献

AbstractIn this review paper, we critically examine the evidence base relating to engagement within the public sector given a wide range of public services have faced acute human resource challenges over recent years. Our review of 188 empirical studies reveals that much of the evidence focuses attention on individual and job level factors, such that specific public sector contextual contingencies have rarely been considered. Through identifying significant ‘context gaps’, we present a future research agenda addressing the following key areas: i) clarifying the relationship between engagement and public service motivation, ii) further contextualizing general engagement models, iii) exploring cultural, socio-political, and institutional factors in more depth, iv) encouraging a more critical perspective on engagement, v) understanding the variation in the experience of engagement across different public services/delivery models, and vi) connecting more strongly with practical concerns and initiatives within public organizations. In presenting this agenda, we highlight how engagement and HRM scholars can more strongly embed their research within a sectoral context. 相似文献

Misinvoicing is a major tool in fraud including money laundering. We develop a method of detecting the patterns of outliers that indicate systematic mis‐pricing. As the data only become available year by year, we develop a combination of very robust regression and the use of ‘cleaned’ prior information from earlier years, which leads to early and sharp indication of potentially fraudulent activity that can be passed to legal agencies to institute prosecution. As an example, we use yearly imports of a specific seafood into the European Union. This is only one of over one million annual data sets, each of which can currently potentially contain 336 observations. We provide a solution to the resulting big data problem, which requires analysis with the minimum of human intervention. 相似文献

The market value of U.S. corporations declined by 50% during 1973–74 and stagnated for the following 15 years. This abrupt decline in market valuations coincided with two technology shocks: (1) the start of the information technology revolution and (2) a sudden slowdown in productivity growth. I use general equilibrium theory to quantify the macroeconomic and asset price implications of these two shocks. The information technology revolution and the productivity slowdown make the theory consistent with the trends of key macroeconomic aggregates from the mid‐1970s to the 1990s, and can also account for most of the drop in market values. 相似文献

Summary This Tinbergen Lecture begins by reviewing empirical evidence about trends in income inequality in a number of Western countries. There is considerable diversity of experience across countries. The first quarter century after the Second World War was not generally characterised by a steady downward trend in inequality, but by episodes of inequality reduction at different dates. More recently, several OECD countries have seen a rise in inequality, but the rates of increase differed and in around half of the countries shown there was no significant upward trend over the 1980s. The differing experiences, and the episodic nature of changes, have implications for the explanations of inequality considered in Sections 2 and 3 of the Lecture. I begin with the mechanism which Tinbergen described in Chapter 6 of hisIncome Distribution: the race between technological development and education. It is argued that behind the supply and demand model there lie a variety of factors, and that the explanation we give may be important in determining whether what we are observing are wagedifferentials or wageinequality. Moreover, we need to consider non-labour income, and Section 3 examines the determination of state transfers and of capital income. Finally, in Section 4, I consider some of the policy implications, focusing on one particular set of policy proposals in which Jan Tinbergen was interested: the idea of a basic income.Ninth Tinbergen Lecture delivered on September 29, 1995 at De Nederlandsche Bank, Amsterdam for the Royal Netherlands Economic Association. 相似文献

Two stochastic nonparametric procedures are developed to evaluate the significance of violations of weak separability. When the data have measurement error, we show that the necessary and sufficient weak separability conditions of Varian [Varian, H., 1983. Nonparametric tests of consumer behavior. Review of Economic Studies 50, 99–110] must also satisfy the Afriat inequalities. The tests detect weak separability with high probability for weakly separable data. In addition, the procedures correctly reject weak separability for both nonseparable and random utility simulated data sets. The tests also fail to reject weak separability for a monetary and consumption data set which suggests that measurement error may be the source of the observed violations. 相似文献

- Door‐to‐door fundraising, where recruiters knock on the door of domestic dwellings to solicit a regular donation, is an increasingly popular recruitment technique. However, reported levels of attrition remain unacceptably high and in some cases charities may lose up to 50% of their new recruits in their first year of giving. In this exploratory study of 5000 active and 5000 lapsed recruits the demographic and attitudinal profiles of each group are compared. The paper concludes that lapsed donors are significantly younger than active recruits and experienced some form of pressure at the point of recruitment. Lapsed supporters were also significantly less happy with the quality of ongoing communication.
