A structural factor model for 112 US monthly macroeconomic series is used to study the effects of monetary policy. Monetary policy shocks are identified using a standard recursive scheme, in which the impact effects on both industrial production and prices are zero. The main findings are the following. First, the maximal effect on bilateral real exchange rates is observed on impact, so that the “delayed overshooting” puzzle disappears. Second, after a contractionary shock prices fall at all horizons, so that the price puzzle is not there. Finally, monetary policy has a sizable effect on both real and nominal variables.  相似文献

Self‐reported life satisfaction is highly heterogeneous across similar countries, a phenomenon that may be explained by the different scales and benchmarks that people use to evaluate themselves. This study uses cross‐sectional data gathered from older populations in ten European countries to compare estimates from a model that assumes reporting styles are constant across respondents against estimates from a model in which anchoring vignettes help correct for individual‐specific scale biases. Variations in response scales explain much of the difference in the raw data. Moreover, the cross‐country ranking in life satisfaction depends significantly on scale biases.  相似文献

This article explores the role of strategic ambiguity as a management practice, as used in SENSEable City Lab – a R&D-oriented lab located at the Massachusetts Institute of Technology in Cambridge, MA. Although literature has already explored strategic ambiguity in various organizational settings, studies focusing on how academic institutions use strategic ambiguity in the context of R&D are quite sparse. The article aims at filling this gap by reporting on a study conducted by the author across 2011 and 2014 in a R&D-oriented academic lab and reflecting on the potential of strategic ambiguity as an effective dialogic strategy to appreciate differences among internal organization members and with external partners. The article also examines some shortcomings of strategic ambiguity, such as the level of anxiety reported by some members of the lab.  相似文献

The most straightforward way to analyze investment‐sector productivity developments is to construct a two‐sector model with a sector‐specific productivity shock. An often used modeling shortcut accounts for such developments using a one‐sector model with shocks to the efficiency of investment in a capital accumulation equation. This shortcut is theoretically justified when some stringent conditions are satisfied. Using a two‐sector model, we consider the implications of relaxing several of the conditions that are at odds with the U.S. Input–Output Tables, including equal factor shares across sectors. The effects of productivity shocks to an investment‐producing sector of our two‐sector model differ from those of efficiency shocks to investment in a one‐sector model. Notably, expansionary productivity shocks boost consumption in every period, whereas expansionary efficiency shocks cause consumption to fall substantially for many periods.  相似文献

ABSTRACT

The market of berries is a niche of high value in Italy. Small fruit’s healthy properties are well known in the international market, but little is known about the reason for a low commercialization rate of fresh small fruit in Italy. The objective of this study was to assess consumer preferences in Italy for selected berry species. Moreover, the study aims to identify the relevant attributes of berries that affect the demand for this produce according to consumers and to compare these attributes. We assessed relevant attributes affecting the demand for fresh berries for different consumers’ profiles and compared berries’ attributes rankings. The results reveal high concordance between blackberries and raspberries; price is the attribute that constrains more purchases because it is deemed too high. Consumers prefer small fruit because of the rising interest in their nutraceutical value, and they have a higher willingness to pay because of this important attribute.  相似文献

Consumer choices are mostly regulated by pleasurable experiences that arise outside of the individuals' awareness in response to sensory attributes. This research examines the unconscious mechanism underlying consumers' behavior in response to odors applying the priming approach. Five experiments show that individuals' responses to odors involve two mechanisms, one affective (affective priming) and one associative (semantic priming) that impact consumers' categorization, recall, and choice. We found that when individuals perceive an odor as pleasant, their memory for odor-congruent brand logos (Experiment 1), and categorization of odor-congruent visual objects (Experiment 2) is improved. Unpleasant odors, instead, improve the categorization of odor-congruent visual objects only when they are made salient (Experiments 3 and 4). A pleasant odor diffused in the environment also drives consumers toward odor-congruent choices (Experiment 5), providing evidence that the incidental exposure to odors may induce affective and semantic associations with unrelated objects and behaviors. We also demonstrate that olfactory cues might be more effective than other modality (visual) stimuli to drive consumer responses. An implication for marketing is that odors employed in retail settings not only may induce an experience of pleasure but also promote specific consumer responses, such as categorization, recall, and choice.  相似文献

We propose a novel identification‐robust test for the null hypothesis that an estimated New Keynesian model has a reduced form consistent with the unique stable solution against the alternative of sunspot‐driven multiple equilibria. Our strategy is designed to handle identification failures as well as the misspecification of the relevant propagation mechanisms. We invert a likelihood ratio test for the cross‐equation restrictions (CER) that the New Keynesian system places on its reduced‐form solution under determinacy. If the CER are not rejected, sunspot‐driven expectations can be ruled out from the model equilibrium and we accept the structural model. Otherwise, we move to a second‐step and invert an Anderson and Rubin‐type test for the orthogonality restrictions (OR) implied by the system of structural Euler equations. The hypothesis of indeterminacy and the structural model are accepted if the OR are not rejected. We investigate the finite‐sample performance of the suggested identification‐robust two‐step testing strategy by some Monte Carlo experiments and then apply it to a New Keynesian AD/AS model estimated with actual US data. In spite of some evidence of weak identification as for the ‘Great Moderation’ period, our results offer formal support to the hypothesis of a switch from indeterminacy to a scenario consistent with uniqueness occurring in the late 1970s. Our identification‐robust full‐information confidence set for the structural parameters computed on the ‘Great Moderation’ regime turns out to be more precise than the intervals previously reported in the literature through ‘limited‐information’ methods.
