The distribution of demand, market structure, and investment in technology

In a quality-ladder growth model, the dispersion in the demand for quality influences the prices innovators may charge for their innovations and the number of such firms that may obtain market shares at any one time. Under a more dispersed distribution, the innovator may only charge a lower price to cover the entire market. The payoff to innovation declines, causing investment to fall. When the dispersion has reached a critical level, the innovator will no longer price out the incumbents, turning the market into a natural oligopoly with firms selling different grades co-existing at any one time, even if it is optimal for all consumers to buy the highest grade available. Any further increases in dispersion raise the payoff to innovation, inducing greater investment.

Rules and Levels in the Provision of Public Goods: The Role of Complementarities between the public Good and Taxed Commodities

This paper revisits the question of whether the second-best level of public good provision is lower than the first-best level in a standard model of public good provision with identical consumers. The role played by the complementarities between the public good and the private commodities is clarified. Furthermore, it is shown that the second-best level is indeed below the first-best level if the Hicksian demands for the taxed commodities are independent of the level of public good provision.     

Managerial myopia and the unintended real consequences of conditional conservatism

We examine whether the demand for conditional conservatism produces unintended real consequences that are exacerbated by managerial incentives to report higher earnings. We document a robust positive association between conditional conservatism and real earnings management (REM), particularly for firms whose CEOs face greater compensation incentives and capital market incentives to report higher earnings. Using mediation analyses, we find that conservatism has a negative indirect relation with future returns via REM over the next 1–3 years. In additional tests, we find that the relation between conservatism and REM is attenuated for firms with higher debt-to-equity, which suggests that debtholders moderate the negative relation between conditional conservative reporting and REM. Our findings suggest that, in contrast to its monitoring benefit, conditional conservatism can exacerbate managerial myopia, resulting in negative consequences for future firm value.     

基于地理探测器的内蒙古耕地水资源短缺时空变化特征及驱动力分析

[目的]明晰干旱半干旱区耕地水资源短缺的时空变化特征及驱动因素，是实现区域水资源可持续利用的首要前提，对保障区域乃至全国粮食安全和生态健康有着重要意义。[方法]文章以内蒙古为典型研究区，以水足迹理论为依据，通过构建耕地水资源短缺指数（Arable Land Water Scarcity Index,AWSI），分析2000—2018年内蒙古耕地水资源短缺指数时空格局及变化特征，并进一步借助地理探测器模型定量揭示研究区内气候、植被、地形、人口密度等11个自然和社会经济因素对耕地水资源短缺时空变化的影响差异。[结果]（1）内蒙古耕地水资源短缺指数总体呈西高东低的分布特征，西部耕地缺水压力较大。2000—2018年内蒙古耕地水资源短缺指数呈增加趋势，增加区域占总面积82%以上，主要分布在东部和中部地区。（2）自然因素主要决定内蒙古耕地水资源短缺的空间格局，其影响明显大于社会经济因素，但是2000—2018年社会经济因素的影响力在呈增大趋势。（3）自然因素中以蒸发量、年均温、降水量为主的气候因子在生态探测中共有19组显著差异，占据了影响因子中的主导地位。而在社会经济因素与自然因素的交互作用下，...     

Cross-national consumer research using structural topic modelling: Consumers' approach-avoidance behaviours

This study introduces structural topic modelling (STM), a sophisticated unsupervised machine-learning algorithm for text analysis, to compare Indonesian and Malaysian Muslim consumers' approach-avoidance behaviours toward Korean beauty products using social media data. The STM results revealed 16 topics for each country, including new common themes belonging to K-beauty culture and wannabe Korean skin. Intriguing differences were also observed between these countries. Korea-related constructs, such as Korea's image and wannabe Korean skin, were approach factors for only Indonesians. Korean cosmetic brand-specific topics were extracted for only Malaysians and were significantly associated with their behavioural responses. Unsuitable Korean beauty products and domestic product preferences were avoidance factors for Indonesians, but new product risks and conflicts between Muslim and Korean cultures for Malaysians. We demonstrate that STM is a helpful tool in cross-national research for corroborating and extending the existing theoretical frameworks. The practical implications are also provided for global marketers.     

Revisiting the valuation of deposit insurance

This study proposes a framework for pricing deposit insurance that evaluates the effect of depositor preference laws and the issuance of contingent capital bonds. Four main findings emerge from this study. First, traditional option pricing models of deposit insurance overestimate insurance premiums. Second, only large issuances of contingent capital bonds decrease deposit insurance premiums under depositor preference. Third, the issuance of contingent capital bonds can partially offset banks' excessive risk-taking caused by regulatory forbearance. Finally, although large banks have implied too-big-to-fail risks, the deposit insurer's costs from large banks are not nearly as high as reported in previous studies.     

The market distortion effects of mortgage tightening and transaction taxes: Evidence from Hong Kong residential resale market

By using transaction-level data, we study if two popular policies intended to cool an overheated housing market would serve their intended purposes. We found both mortgage tightening and Special Stamp Duties (SSD) actually led to higher starter home prices in Hong Kong. Mortgage tightening shifted the demand for bigger homes to that for smaller ones. The SSD that applies to resales within a specified period of the original purchase lowered turnover across the housing market. The decline in turnover is, as expected, sharpest for small flats, implying a dramatic shrinkage in second-hand supply of such homes, driving their prices up. We also found transactions bunching as many homes are held till the SSD is no longer applicable, indicating lock-in effects. Relative to those that are not subject to the SSD, the prices of properties subject to the levy are found to be lower by 6.8%.     

Trade patterns and institutional change in East Asia

We investigate how trade patterns – institutionally intensive exports (IIX) – affect institutional quality in East Asia compared to the rest of the world, and whether the effect changed due to the Asian financial crisis. To examine this, we use panel data of 117 countries for the period 1988–2007. Our fixed effect model estimation reveals that the effect of IIX on institutional quality is negative and significant for East Asia, while the effect is insignificant for the rest of the world. The negative effect in East Asia is more pronounced for the five East Asian countries that were strongly affected by the crisis – South Korea, Indonesia, Malaysia, the Philippines and Thailand – than for other East Asian countries. Furthermore, our results reveal that the negative effect for East Asia does not change significantly after the crisis, both in the short and long term, and that improvement in institutional quality after the crisis is not different from that of the rest of the world. This suggests that the crisis had no significant impact on East Asia's institutional quality or on the effects of IIX on institutional quality.     

It is different than what I saw online: Negative effects of webrooming on purchase intentions

Webrooming is a two-stage shopping process that begins with examining product options online followed by making a purchase at an offline store. In four experiments, we investigate webrooming effects on product evaluation and purchase intentions. The results suggest that webrooming (vs. non-webrooming) has negative impacts on (1) perceived product performance vis-à-vis expectations and (2) purchase intentions for the products offline. Our moderated-mediation analyses show that webrooming leads to lower perceived product performance, which in turn results in lower purchase intentions, and participants’ Need for Touch (NFT) moderates the negative mediation effect, which is stronger with instrumental NFT than autotelic NFT. However, this moderated-mediation effect is attenuated when products are searched across multiple categories. These findings contribute to the marketing literature by providing a more nuanced understanding of how two-stage, webrooming behavior affects consumers’ cognitions and purchase decisions. They also provide several managerial implications that when controlling for time intervals between the stages, (1) webrooming may adversely affect retailers’ business outcomes when webrooming within a single (e.g., blankets), related (e.g., baby products), and unrelated product categories; (2) thus, creating an integrated online-to-offline cross-channel customer experiences is critical to minimize the negative webrooming effects on final sales.
