This paper studies the effect of firm entry deregulation on the returns to skill and education. We exploit a comprehensive episode of entry deregulation, unique in the industrialized world, as a quasi-natural experiment. Using matched employer–employee data for the universe of workers and firms in Portugal, we show that increased product market competition, which resulted from deregulation, increased the returns to a university degree and the returns to skill. We verify that our results are not driven by changes in employment composition, and are unlikely to be driven by skill-biased technical change, or by workers who change skill levels after the deregulation.  相似文献

This article explores and theorizes the ways in which urban space and political contestations are mapped onto each other. The ethnography illustrates the multifaceted transformations in a notoriously secularist neighborhood of ?stanbul, Te?vikiye, as it first turns into a high‐consumption locality in the post‐1980s, then into a high‐conflict urban space in the new millennium on the arrival of Muslim high‐spenders, particularly headscarved women. Aiming to fill the gap left by the absence of spatial analysis from political science and political sociology, I argue that the urban neighborhood becomes central for political contestation when both government and opposition fail to protect and secure liberties and rights. Now that devout Muslims are integrated into highly contested urban sites and share bourgeois lifestyles, ordinary people act in defense of their ‘sphere’ of freedom and privacy. This new territoriality is largely symptomatic of increasing fears of losing freedom, privacy and social status. This spatial defensiveness is reinforced by people's decreasing trust in, and increasing demands from, the state for the protection and security of their rights and liberties. My overarching argument is that exclusive attention to the bipolar clash between devout Muslims and secularists under the rubric of ‘neighborhood wars’ obscures multipolar conflicts around the discontents stemming from authoritarianism and democratization.  相似文献

从征税效果和效率的视角,对资源税从价征收进行了预评价。评价结果表明,从价计征改革存在2大局限性,一方面无法达到"地方政府摆脱资源大省、财政小省困境"和"提高回采率、保护煤炭资源"等预期效果;另一方面,会造成征税的双重超额负担,导致征税低效率。在此基础上,建议应从整体而非局部推动煤炭资源税费改革,系统地进行煤炭资源税收体系再设计。  相似文献

In the conceptual framework of adaptation policy assessment to climate change, adaptation measures can be categorized as two groups:facilitation and implementation. Facilitation measures refers to activities that enhance adaptive capacity, while implementation refers to activities that actually avoid adverse climate impacts on a system by reducing its exposure or sensitivity to climatic hazards, or by moderating relevant non-climatic factors. This paper aims to establish a matrix of implementation measures of adaptation to climate change, through four different ways how adaptation can influencc the relevant elements of climate change. reducing the exposure, reducing the sensitivity, alleviating the adverse impacts and reducing the negative non-climatic factors, and then further discuss the particular implementation measures of adaptation to climate change, through application studies on the selected sub-systems, intend to organize the disordered implementation measures in existent, and put forward some new measures under the guidance of this matrix, which could enrich and promote the system and content of implementation measures of adaptation.  相似文献

目前,旅行社扭曲的经营模式是以不合理的购物佣金为基础的,这种购物佣金也几乎必然损害旅游者权益.当前的治理方式主要有两种,即立法禁止与立法规范.但两者都没能解决问题,其共同的困境在于:第一,都是地方立法,受限于地方利益的顾虑,执法者不可能严格执法;第二,都过度依赖行政监管,但行政监管存在自身固有的不足.可行的解决思路是在旅游法中赋予旅游者一项合适的权利,通过旅游者有效的维权活动制约旅行社损害旅游者利益的佣金行为.购物反悔权正是这样一种合适的权利,它将迫使旅行社主动将购物佣金控制在旅游者可以接受的限度内,或者干脆放弃购物安排.此时行政监管的主要职责将转化为保障旅游者该项权利的顺利实现,借此形成市场主导、行政保障的治理模式.  相似文献

The present study examines the effect of using a mobile device on search and evaluation by a shopper in a brick-and-mortar store. A conceptual model that proposes inter-relationships between shopping goals, the amount and type of in-store mobile device use, and purchase outcomes is developed. Data from a national quota sample of 1034 mobile shoppers is used to test hypotheses derived from the proposed model. The findings provide several new insights into the impact of in-store mobile device use on the consumer decision journey in a brick-and-mortar store. Depending upon the shopping goals of the consumer, the use of a mobile device by shoppers in a brick-and-mortar store can either decrease or increase search, lead to more deferred purchases or in-store-now purchases, and more online or physical store purchases. The study is among the first to model the pathway to purchase for mobile device assisted shoppers in brick-and-mortar stores.  相似文献

In today’s online environment, consumers and sellers interact through multiple channels such as email, search engines, banner ads, affiliate websites and comparison-shopping websites. In this paper, we investigate whether knowing the history of channels the consumer has used until a point of time is predictive of their future visit patterns and purchase conversions. We propose a model in which future visits and conversions are stochastically dependent on the channels a consumer used on their path up to a point. Salient features of our model are: (1) visits by consumers are allowed to be clustered, which enables separation of their visits into intra- and inter-session components, (2) interaction effects between channels where prior visits and conversions from channels impact future inter-session visits, intra-session visits and conversions through a latent variable reflecting the cumulative weighted inventory of prior visits, (3) each channel attracts inter-session and intra-session visits differently, (4) each channel has different association with conversion conditional on a customer’s arrival to the website through that channel, (5) each channel engages customers differently (i.e., keeps the customer alive for a next session or for a next visit within a session), (6) the channel from which there was an arrival in the previous session can have an enhanced ability to generate an arrival for the same channel in the current session (channel persistence), and (7) parsimonious specification for high dimensionality in a low-velocity, sparse-data environment. We estimate the model on easy-to-collect first-party data obtained from an online retailer selling a durable good and find that information on the identities of channels and incorporation of inter- and intra-session visits have significant predictive power for future visitation and conversion behavior. We find that some channels act as “closers” and others as “engagers”—consumers arriving through the former are more likely to make a purchase, while consumers arriving through the latter, even if they do not make a purchase, are more likely to visit again in the future or extend the current session. We also find that some channels engage customers more than others, and that there are interaction effects between the channels visited. Our estimates show that the effect of prior inventory of visits is different from the immediate prior visit, and that visit and purchase probabilities can increase or decrease based on the history of channels used. We discuss several managerial implications of the model including using the predictions of the model to aid in selecting customers for marketing actions and using the model to evaluate a policy change regarding the obscuring of channel information.  相似文献
