Using data for actual insider trading cases prosecuted by the Securities and Exchange Commission, the paper aims to investigate whether insiders trade strategically to avoid detection.

The paper analyzes actual insider trades prior to price sensitive announcements.

It is found that insiders are more likely to trade on high volume days, which indicates an effort to hide their trades. Further, insider trading raises the number of days with abnormally high trading volume only slightly, again indicating that insiders are avoiding attracting attention. No evidence is found that insider trading intensity increases on the insider trading day closest to the announcement day. The hypothesis that index returns for insider trading days and non‐trading days are the same cannot be rejected, which is consistent with insiders avoiding detection. For stocks sold by insiders, returns are higher for insider trading days than for non‐insider trading days. Hence, insiders are selling on days when the market is up, which tends to hide their trading. But for stocks bought by insiders, returns are significantly higher on insider trading days than on non‐insider‐trading days, indicating that in this case insiders may attract unwanted attention.

The research may be useful to those attempting to detect insider trades.

This article is premised on the idea that social networks represent an important, but often overlooked, unit of analysis in management and entrepreneurship studies. The concept of embeddedness, emphasizing the significance of social relationships, is of particular relevance as more and more frequently minorities and immigrants engage in small businessownership. This article borrows from the ethnicity and social network traditions, and offers that an analysis of the ethnic homogeneity of an entrepreneur's strong and weak social ties would be fruitful in gauging entrepreneurial success.

Considers the pluralistic cultures which exist within a nation and outlines the history of previous research into this field. Introduces the concept of embeddedness which means that the society within which a person lives will influence their behaviour. Discusses intracultural differences and presents some research strategies for looking at the ethnic consumer.

The purpose of this paper is to review the study of social capital focused on the level at which it is embodied, cross-comparing two prominent camps that have emerged in the social capital literature: a communal level and an individual level.

This paper reviews the intersections and departures between communal level and individual level conceptualizations of social capital according to the social dynamics of action within social exchanges that they stimulate, the processes by which social capital is activated/mobilized and the rewards they yield, and their linkages to inequality through network diversity.

This paper articulates new directions for future research in social capital: more analytical precision for studying returns to social capital; more efforts to transcend the individual-communal divide; the depreciation of social capital or tie decay; and recognizing the importance of ties whose value does not come from the ability to provide instrumental gain, but just from their very existence.

Social capital has informed many influential agendas in the social sciences, but the sheer volume of which has largely gone unscoped. This paper reviews this literature to provide an accessible introduction to social capital, organized by social processes foundational to sociology and a novel contribution to the literature by articulating new directions for future research in the area.

Analysis of organizational decline has become central to the study of economy and society. Further advances in this area may fail however, because two major literatures on the topic remain disintegrated and because both lack a sophisticated account of how social structure and interdependencies among organizations affect decline. This paper develops a perspective which tries to overcome these problems. The perspective explains decline through an understanding of how social ties and resource dependencies among firms affect market structure and the resulting behavior of firms within it. Evidence is furnished that supports the assumptions of the perspective and provides a basis for specifying propositions about the effect of network structure on organizational survival. I conclude by discussing the perspective’s implications for organizational theory and economic sociology.

Empirical studies show substantial variation across immigrants in the rate and direction of assimilation along various dimensions (e.g., cross-ethnic contact, language, identity). To explain this variation, past research has focused on identifying exogenous factors, such as discrimination, human capital, and settlement intention. In this chapter we argue that variation in immigrant outcomes emerges endogenously through positive interaction effects between dimensions of assimilation. We propose a new assimilation model in which processes of social influence and selection into congruent social environments give rise to multiple long-term equilibria. In this model, migrants who are already assimilated along many dimensions tend to also adapt along other dimensions, while less assimilated migrants become more strongly embedded in their ethnic group.

To test the assimilation model, we derive a number of hypotheses, which we evaluate using trend analysis and dynamic panel regression on data from the Longitudinal Survey of Immigrants to Canada.

The data mostly confirm the hypotheses, providing overall support for the assimilation model.

Our theory and findings suggest that immigrants would follow divergent assimilation trajectories even in the absence of a priori population heterogeneity in external factors.

The positive interaction effects between cultural and structural dimensions of assimilation suggest that mixed policies that promote integration while seeking to prevent loss of identity go against the natural tendency for cultural and structural assimilation to go hand in hand.

The present chapter proposes a novel model of immigrant assimilation and an empirical test.

Recent scholarship has highlighted the complexity of buyer-seller relationships in emerging markets and called for a better understanding of the cultural norms shaping such relationships. This paper aims to draw on social capital theory to explore the role of networks and relational norms, such as wasta, in Arab culture on consumer relational behaviors. The Arab market constitutes a significant economy and social networks and relational norms are of significant value in Arab culture.

A qualitative approach was used to address the research questions. In-depth semi-structured interviews were conducted with 19 male and female consumers across Lebanon over a four-month period.

Social networks are heavily used in relational behaviors to achieve four types of goals, namely, self-serving goals, unity goals and equality goals and relationship maintenance goals. In fulfilling these goals consumers create economies of favors that aim at the using and maintenance of communal bonds.

This study was conducted in one geographical context. While Lebanon shares many of its characteristics with other Arab countries, future research should aim at exploring the influence of social networks in other Arab and emerging market contexts.

Consumers have different motivations between formal and informal markets. The research suggests that small sellers in highly embedded markets need to use their social networks and to make their stories authentic and known within their communities to facilitate emotional connections with consumers.

Emerging markets offer opportunities to extend our understanding of marketing theory and practice. This research provides a richer understanding of Arab consumers and suggests that wasta relationships play a role in consumptive decisions and not just in business negotiations. Wasta, as a cultural form of cultural capital, is heavily used in consumption as a coping mechanism to overcome market inefficiencies.
