In this paper, we demonstrate the complexity of consumer decision-making within the supermarket and use videographic techniques to gain greater insight into this. We propose that grocery shopping, often perceived as a routine behavior, can in fact, become quite complex. The broad pattern emerging from our study was that the less time the participant spent looking at the shelves, the less emotion displayed. Where there was longer time spent, there was also increasing physical interaction with the product and a greater display of mostly negative emotion. We suggest that this presents a conundrum for retailers. Does the lack of emotion indicate little or no commitment to the store and/or brand? Or are they so loyal there is no need for consumer engagement? This exploration suggests that further insight can be gained if the emphasis is on how the consumer interacts with their brands rather than assuming that all grocery decisions are predictive.  相似文献

Most econometric models of intrahousehold behavior assume that household decision making is efficient, i.e., utility realizations lie on the Pareto frontier. In this paper, we investigate this claim by adding a number of participation constraints to the household allocation problem. Short-run constraints ensure that each spouse obtains a utility level at least equal to what they would realize under (inefficient) Nash equilibrium. Long-run constraints ensure that each spouse obtains a utility level at least equal to what they would realize by cheating on the efficient allocation and receiving Nash equilibrium payoffs in all successive periods. Given household characteristics and the (common) discount factor of the spouses, not all households may be able to attain payoffs on the Pareto frontier. We estimate these models using a Method of Simulated Moments estimator and data from one wave of the Panel Study of Income Dynamics. We find that both short- and long-run constraints are binding for sizable proportions of households in the sample. We conclude that it is important to carefully model the constraint sets household members face when modeling household allocation decisions, and to allow for the possibility that efficient outcomes may not be implementable for some households.  相似文献

We use the regional and time variation of training grants in Italy to identify the causal effect of (formal continuing vocational) training on earnings. We estimate log-linear earnings regressions with constant marginal returns to training and find that one additional week of training increases monthly net earnings by 1.36%, substantially less than the 3% or more often found in the literature. Estimated returns vary significantly by firm size, and range from 0.40% in firms with more than 100 employees to 2.51% in smaller firms, the bulk of the Italian private sector. A simple back of the envelope comparison of the marginal costs and benefits of training policy suggests that the latter are higher than the former.  相似文献

Countless experimental studies have shown that markets converge quickly and efficiently to the competitive outcome under many trading institutions, particularly the double auction mechanism. This creates difficulties for Keynesian stories of unemployment creation—which suggest a noncompetitive outcome in an essentially competitive world. Such stories were popular in the late 1960s and 1970s. One of these stories—the dual decision hypothesis of Clower—was seen then as the beginning of a story of unemployment. This article reports the results of an experiment designed to test this hypothesis. Specifically, we set up an experiment in which there are two sequential double-auction markets, in the first of which one good (labour) is traded, after which the second market (goods) is opened and the second good traded. We compare the outcome of our experiment with that of the competitive theory. One general finding is that not enough trade takes place in the two markets. In other words, the usual finding that competitive equilibrium is achieved in double-auction markets is not replicated in this sequential setting. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献

In this paper, I interpret a time series spatial model (T-SAR) as a constrained structural vector autoregressive (SVAR) model. Based on these restrictions, I propose a minimum distance approach to estimate the (row-standardized) network matrix and the overall network influence parameter of the T-SAR from the SVAR estimates. I also develop a Wald-type test to assess the distance between these two models. To implement the methodology, I discuss machine learning methods as one possible identification strategy of SVAR models. Finally, I illustrate the methodology through an application to volatility spillovers across major stock markets using daily realized volatility data for 2004–2018.  相似文献

We examine the influence of CEOs’ equity and cash grants’ vesting provisions that are based on (i) accounting performance metrics prepared under US generally accepted principles (GAAP), (ii) non-GAAP performance metrics and (iii) key performance indicators (KPIs) on debt contracts. We find that grants with vesting provisions based on GAAP metrics and KPIs lead to a lower cost of debt, a lower likelihood of collateral requirements and less restrictive covenant terms. In contrast, performance-based grants with non-GAAP vesting provisions lead to a higher cost of debt, a higher likelihood of collateral requirements and more restrictive covenant terms. Supplementary analyses reveal that our results are incremental to other debtholder-friendly features in the CEO contracts, such as grants with debt-related performance measures and CEOs’ inside debt holdings, and robust to alternative variable definitions and specifications. Overall, our results suggest that debtholders understand the differing incentives associated with GAAP, non-GAAP and KPI-based performance measures, and incorporate these differences into debt contracts.  相似文献

Systemic liquidity risk, defined by the International Monetary Fund as “the risk of simultaneous liquidity difficulties at multiple financial institutions,” is a key topic in financial stability studies and macroprudential policy-making. In this context, the complex web of interconnections of the interbank market plays the crucial role of allowing funding liquidity shortages to propagate between financial institutions. Here, we introduce a simple yet effective model of the interbank market in which liquidity shortages propagate through an epidemic-like contagion mechanism on the network of interbank loans. The model is defined by using aggregate balance sheet information of European banks, and it exploits country and bank-specific risk features to account for the heterogeneity of financial institutions. Moreover, in order to obtain the European-wide topology of the interbank network, we define a block reconstruction method based on the exchange flows between the various countries. We show that the proposed contagion model is able to estimate systemic liquidity risk across different years and countries. Results suggest that our effective contagion approach can be successfully used as a viable alternative to more realistic but complicated models, which not only require more specific balance sheet variables with high time resolution but also need assumptions on how banks respond to liquidity shocks.

The paper proposes an analysis of entrepreneurial intentions in the equine sector in Romania and the identification of the variables influencing economic growth in this field. The equine sector plays a strategic role in the development of durable, sustainable and social entrepreneurship. The combination of equine services can ensure a business's survival during a crisis, and businesses involving horses can be considered complex. The equine sector is constantly changing: it is affected by politics, the social environment and new competitors. Changing customer requirements make it a difficult area in which to develop a sustainable start-up ecosystem. The present study is important in drawing attention to the main impediments faced by Romanian entrepreneurs in the development of the equine sector, a sector which—because of the emotional and physical benefits that horses offer—has great potential. The horse industry needs true "enthusiastic entrepreneurs" who have the management knowledge and skills to make their business more professional and profitable. It was found that the firm's organisation method is an important factor in predicting business continuity, in achieving medium- and long-term objectives, and in ensuring business success.
