Speed under sail during the early industrial revolution (c. 1750–1830)

This article measures technological progress in oceanic shipping directly by using a large database of daily log entries from British, Dutch, and Spanish ships to estimate daily sailing speed in different wind conditions from 1750 to 1850. Against the consensus among economic (but not maritime) historians that the technology of sailing ships was fairly static during this time, we find that average sailing speeds of British East India Company and Navy ships in moderate to strong winds rose considerably after the 1770s. Driving this progress was the introduction of coppering in the 1780s, but subsequent rises are probably due to a continuous evolution of sails and rigging, and improved hulls that allowed a greater area of sail to be set safely in a given wind. By contrast, the speeds of Dutch and Spanish vessels were stagnant. Using separate data on the crossing times of Atlantic mail packets, we find gradual progress from the 1750s, followed by marked improvements when American packets appeared in the 1820s.     

CONTINUOUS PREFERENCE ORDERINGS REPRESENTABLE BY UTILITY FUNCTIONS

This paper surveys the conditions under which it is possible to represent a continuous preference ordering using utility functions. We start with a historical perspective on the notions of utility and preferences, continue by defining the mathematical concepts employed in this literature, and then list several key contributions to the topic of representability. These contributions concern both the preference orderings and the spaces where they are defined. For any continuous preference ordering, we show the need for separability and the sufficiency of connectedness and separability, or second countability, of the space where it is defined. We emphasize the need for separability by showing that in any nonseparable metric space, there are continuous preference orderings without utility representation. However, by reinforcing connectedness, we show that countably boundedness of the preference ordering is a necessary and sufficient condition for the existence of a (continuous) utility representation. Finally, we discuss the special case of strictly monotonic preferences.     

Distributional effects of social security reforms: The case of France

This paper assesses the impact of two social security reforms using a calibrated, dynamic life cycle model. It quantifies the long‐run distributional impact of two sets of reforms in France: (1) the 2013 reform of Prime Minister Ayrault, which modified the parameters of a defined benefit (DB) plan, and (2) a hypothetical reform that changes the system to a notional defined contribution (NDC) plan, similar to that in Italy. First, on aggregate welfare, the Ayrault reform and the hypothetical switch to NDC yield contrasting results. The Ayrault reform improves aggregate welfare, which is not the case for the NDC reform. Welfare comparisons are made with respect to the “benchmark economy,” where increases in life expectancy occur and are dealt with only through a higher contribution rate. Second, both reforms yield unequal distributions of welfare changes, with low‐skill workers on the losing end. Under the Ayrault reform, low‐skill workers delay retirement by two years, to age 62. Under NDC reform, pensions for low‐skill workers fall substantially as inequalities during the work life translate directly into inequalities in pensions. The switch to an NDC scheme leads to a more unequal society in terms of asset and welfare distribution.     

Stock Market Reaction to Monetary Policy: An Event Study Analysis of the Brazilian Case

This article examines the relationship between the monetary policy implemented by the Central Bank of Brazil and the stock market. We implement event study analysis and analyze the effect of the anticipated and unanticipated components of monetary policy decisions on the returns of the IBOVESPA index and 53 stocks. We find that monetary policy has a significant effect on the stock market, but is only responsible for a small proportion of market variation. The analysis at the sector level with expected returns identifies that the financial sector is the most affected by this policy, whereas with excess returns only industrial goods are significantly affected. Moreover, individual assets respond in a rather heterogeneous fashion to monetary policy; however, when we look at excess returns, we identify a reduction in the intensity and in the number of companies impacted by monetary policy. Finally, the monetary shock is explained by unanticipated variations in the unemployment rate, in the Industrial Production Index, in the General Market Price Index, and in the Broad Consumer Price Index.     

Marketing firm performance: When does marketing lead to financial gains?

The research investigated whether economic context and prior financial reinforcement/punishment moderate the effectiveness of marketing behavior in generating gains for the firm. An experiment with a longitudinal design was conducted using 1,759 companies from 2000 to 2017. The results demonstrate that marketing is effective in gaining market share when the country's economy is growing. In contrast, it increases return on assets and Tobin's Q when the country's economy is in recession, this increase being maximized when the company was financially reinforced. The study helps explain the circumstances in which marketing activities boost firms' financial gains.     

媒体情绪与房价波动*

本文使用2000—2015年中国112个大中城市媒体报道和房价月度指数研究了媒体异质性对房价波动的影响。研究发现，纸媒情绪对房价波动的影响大于网媒情绪，中央媒体情绪对房价波动的影响大于地方媒体情绪，明星微博情绪对房价波动的影响大于普通微博情绪，媒体语气确定性和报道篇幅对房价波动有正影响，明星城市媒体情绪较非明星城市更易引起房价波动。据此，为防范非理性房价波动，应加强对不同媒体报道的监管。     

Financial capability of student loan holders who are college students,graduates, or dropouts

Effective consumer financial education provides relevant information to meet special needs of targeted audiences. The purpose of this study is to examine differences in financial capability among student loan holders who are college students, graduates, and dropouts. Using data from the 2015 U.S. National Financial Capability Study, the results show that student loan holders who have completed their education program have higher scores in all financial capability indicators than college students and dropouts. Further analyses show differences in specific financial knowledge items among college students, graduates, and dropouts. In addition, college graduates are more likely to perform several specific desirable financial behaviors than college students and dropouts. The findings suggest that financial educators should emphasize action taking when they provide financial education for student loan holders who are college students and dropouts.     

Taking services to foreign markets: A taxonomy of Brazilian service firms

This study develops a taxonomy of international service firms from an emerging market, Brazil, and assesses whether there are significant differences in international performance between the groups. After an extensive literature review, a survey was carried out with a sample of international service firms located in an emerging economy, Brazil. Using as a departure point two theoretical perspectives, the internationalization process theory and industrial organization theory, in addition to service dimensions extracted from the empirical service management literature, the study identifies four groups—large traditionals, generalist neophytes, solitary traditionals, and daring differentiators—based on firm characteristics, international services delivered, internationalization process characteristics, and international strategies adopted. The findings suggest that there are significant differences in performance between the groups.     

Corporate Frauds as Criminal Business Models: An Exploratory Study

In this article, we report on the findings of an exploratory, interpretive study of a notorious corporate fraud that occurred in Brazil from 1989 to 2005. We examine the process by which this scheme was created as well as how it was maintained for all those years. Our analysis covers both the substantive aspects (the actions fraud agents effectively perform) and the symbolic aspects (the resources of impression management that they use). We suggest that under certain circumstances, corporate frauds may be understood as the result of implementation of a criminal business model that focuses on a niche market of risk takers or greed investors, uses aggressive commercial practices and offers exclusivity, promotes the organization's image and personality cult of the entrepreneur, operates a management model that combines centralized control with fragmented systems, and uses complex fraudulent practices. This perspective allows us to understand the phenomenon of corporate fraud from a systemic point of view. We also suggest directions for future research and theory development on corporate frauds. © 2014 Wiley Periodicals, Inc.     

Opportunities to Improve Entrepreneurship Education: Contributions Considering Brazilian Challenges

This paper identifies challenges and opportunities for enhancing higher education in entrepreneurship considering student perceptions concerning both their demand for entrepreneurship education and their entrepreneurial intention as well as previous studies that present the points of view of experts. The main focus is Brazilian higher education, but the results address challenges that cross borders, such as the need for a practical approach. The study analyzed the data from the Brazilian version of the 2011 Global University Entrepreneurial Spirit Students' Survey (GUESSS) obtained with an online questionnaire answered by 25,751 Brazilian students from 37 colleges and universities. To give a reference for a better understanding of Brazilian statistics, data were compared to those of the 2011 international GUESSS involving also 25 other countries and 64,079 responses from them. Three hypotheses were tested. The results show that entrepreneurship education has a significant negative effect on student entrepreneurial intention and also on self‐efficacy. The same occurs between entrepreneurial intention and students' demand for entrepreneurship education. Brazilian students present higher levels of entrepreneurial intention and are significantly more motivated to take courses and activities in entrepreneurship than those students in the international sample. Approximately 50 percent of Brazilian students are potential entrepreneurs. One of the opportunities identified is to take advantage of students' positive attitudes and their high demand. The opportunities could play an important role in overcoming the challenges recognized, among which are the need for a more practical approach and the need for larger and diversified educational offerings beyond business planning. The challenges make Neck and Greene's recommendations, presented in a 2011 issue of JSBM, particularly important for Brazil. The last three sections propose different explanations, suggestions for more research, and practical recommendations.
