Between the 1970s and the 2000s, Costa Rica became established as the world’s leading ecotourism destination. This article argues that although Costa Rica benefited from biodiversity and a pleasant climate, the country’s preeminence in ecotourism requires more than a natural resource endowment explanation. While previous literature has emphasized the efforts of the government and nongovernment organizations, this article demonstrates the critical role of small entrepreneurs in the co-creation of the industry. Making extensive use of oral history, the article explores the role of tour companies in drawing affluent Western ecotourists to the country, and of the creators of ecolodges and other forms of accommodation in providing them with somewhere to stay. Clustering created positive externalities, drawing new entrepreneurs into the industry who could also learn from knowledge spillovers. There were downsides to the new industry. The creation of the national image of a natural paradise enabled many businesses which were not environmentally sustainable to free ride on the green image.

This article revisits the story of one the greatest financial frauds in history: Poyais. In the 1820s, Gregor MacGregor issued bonds for this alleged fictitious Central American state on the London capital market. Putting together scattered evidence reveals a complex, multifaceted experiment undertaken by a private adventurer hoping to politically and economically position himself in a changing world. Poyais was a failed project to establish a settlement on a territory granted by an Indigenous leader and financed through British capital markets. Studying a financial failure provides nuanced insights into the political and legal frameworks defining origination processes of early nineteenth-century foreign loans. Following MacGregor’s actions entails drawing a story with contours that extend well beyond the City of London, revealing a rich set of transatlantic actors and spaces not known to be traditionally linked to the London-based capital market. The story of Poyais constitutes a window into the early financial dynamics of private colonialism and how these contributed to British imperial expansion. The Poyais loan appears as constituting a financial endeavor born from the encounter of different “worlds,” with MacGregor mediating these together but ultimately failing to legally and politically guarantee their lasting encounter.
