名人故居：大北京的“小地方”

北京是著名的旅游城市，知名景点有很多，但正是因为有这些知名景点，让很多人忽略了北京一些颇有人文底蕴的“小地方”。作为历史文化名城，在北京居住过的名人数不胜数，他们留下的故居可谓北京一景。虽然这些名人故居比起故宫、颐和园，是不折不扣的“小地方”，但若置身其间，细细品味，其特有的历史厚重感和浓郁的文化气息，却令人回味无穷。     

Collective Wage Contracts,Opt‐Out Clauses,and Firm Wage Differentials: Evidence from Linked Employer–Employee Data

Using a large linked employer–employee data set, this article studies whether the existence and use of flexibility provisions within centralized collective wage agreements alter the structure of pay across employers. Using level regressions and first‐difference methods, we find that—compared with contracts without any flexibility—wages under opt‐out clauses are more responsive to local profitability conditions in below‐average‐performing establishments. In contrast, the sensitivity of wages to local profitability is smaller in high‐performance establishments. Our results provide further evidence for a threat potential of the existence of opt‐out clauses whose impact on flexibility is larger than the real application.     

Skill Level and Recreation Conflict among Skiers and Snowboarders

This paper examines out-group and in-group normative beliefs about unacceptable behaviors (conflict) reported by skiers and snowboarders with varying skill levels. Individuals with greater skills in skiing and snowboarding were predicted to experience more conflict than those with less ability in the activity. Across all skill levels, skiers and snowboarders were hypothesized to report more out-group than in-group conflict. Data were obtained from surveys (n = 595) distributed at five ski resorts in Colorado. Skiers and snowboarders rated their skill level on a four-point scale (beginner, intermediate, advanced, or expert). Multiple item indices were created to measure observed unacceptable behaviors between skiers and snowboarders. Analyses supported both hypotheses. As perceived skill level increased, out-group and in-group conflict increased for both skiers and snowboarders. Within each skill level, skiers reported more unacceptable behaviors by snowboarders than with fellow skiers, and snowboarders also identified more out-group than in-group conflict.     

Product Market Competition and Human Resource Practices in the Retail Food Sector

In the wake of Wal‐Mart and other mass merchandisers’ entry into food retailing, the nature of competition in the industry has changed radically. Using longitudinal data on workers and firms to construct measures of compensation and churning for traditional food retailers, this paper examines how these measures change in response to mass merchandiser entry. While there is considerable heterogeneity across retail food establishments, human resource practices are persistent even in the face of new external competition.     

Investor Behavior and the Benefits of Direct Stock Ownership

Using an experiment to rule out reverse causality, we examine whether a small investment in a company's stock leads investors to purchase more of the company's products and adopt other views and preferences that benefit the company. We preregister our research methods, hypotheses, and supplemental analyses via the Journal of Accounting Research’s registration‐based editorial process. We find little evidence consistent with these hypotheses for the average investor in our sample using our planned univariate hypothesis tests, and planned Bayesian parameter estimation shows substantial downward belief revision for more optimistic ex ante expectations of the treatment effects. In planned supplemental analyses, however, we do find that the effects of ownership on product purchase behavior and on regulatory preferences are intuitively stronger for certain subgroups of investors—namely, for investors who are most likely to purchase the types of products offered by the company and for investors who are most likely to vote on political matters. The results contribute to our understanding of the benefits of direct stock ownership and are informative to public company managers and directors.
