Primitive Accumulation In The Late Twentieth Century: Mexico, The United States, And Nafta, Mark Huffman

Scholars Week

Between 1971 and 1994, American capital succeeded in redirecting state action toward the interests of the largest transnational firms, facilitating extreme concentrations of wealth and capital alongside a profound defeat of organized labor and the dismantling of social programs. The post-Keynesian political economy produced the North American Free Trade Agreement, an event which demonstrated both the ideological capture of the American state by neoliberalism and the purpose of the ideology as a social force (as opposed to a strictly economic one). This article investigates the neoliberal turn generally and NAFTA specifically as engines of social dislocation in North America and …

Authenticity Assurance: Risk Aversiveness & Authenticity Signaling In Local Product Evaluation, Sidney B. Lasley

Scholars Week

Local products are commonly associated with attributes that contribute to perceptions of authenticity such as ethical values, simplicity, and community embeddedness. However, the characteristics often associated with local businesses, such as small scale, informality, and limited standardization, may be signals of uncertainty regarding quality, consistency, or reliability. As a result, perceptions of authenticity for local products may vary across consumers depending on their sensitivity to risk. Across two studies, we examine how risk aversiveness influences perceptions of authenticity and subsequent purchase intentions in a local product context. Study 1 uses survey data to show that authenticity mediates the relationship between …
