Crescimento econômico secular no Brasil, modelo de thirlwall e termos de troca

Explaining the Brazilian economic growth performance during the 20th is a challenging task to academics. As shown, Brazil had already experienced faster growth and recently it is far from such belle époque. Most explanation lies on conventional frameworks. This paper assesses the Thirlwall’s balance-of-payments constraint model to Brazilian economic growth in the period 1900-2005, highlighting the importance of the terms of trade. The results show, first, that the terms of trade are significant in the estimation of import demand function and change the income elasticity, especially in the first period of the sample (1900-1970), and, second, when the simplest Thirlwall’s model is controlled by terms of trade, it seems that such variable is important through export growth, which cause changes in economic performance.

Allocation of authority in franchise chains

This article investigates the level of delegation in franchise chains, distinguishing the two most relevant franchising models: Business Format Franchising and Learning Network Franchising. The two models basically differ on the level of real authority (effective control over decisions) exercised by the franchisors. Differences in business features, such as the required standardization, monitoring costs and consumer sensitivity to variations in product attributes (consumer measurement costs), explain the adoption of the different models of franchising. These variables affect the trade-off between the risk of brand name loss and the gains in knowledge sharing and learning within the network. The higher the need for standardization, the higher is the risk of brand name loss, and, consequently, the more likely the franchisor will adopt an organizational design that confers more control over franchisees’ decisions, such as business format franchising. This paper presents two case studies with Brazilian food franchise chains that illustrate the main argument and suggest additional propositions. Moreover, an empirical analysis of 223 franchise chains provides additional support to the hypothesis of a negative the effect of required standardization on the level of delegation.
