Abstract

This paper develops a three-sector economic growth model of a small open economy with imported goods and tariff. The three are the industrial, service and public sectors. The model also introduces the impact of externalities, congestion and effects of the public good on the productivities. The model integrates a few well-known models in the literature of economic growth in a comprehensive framework. These models include Solow’s growth model, Uzawa’s two-sector growth model, the neoclassical growth models of small-open economies, and the growth models with externalities, public good, and congestion. The study focuses on the effects of changes in the tariff rate, preference for foreign good, the global change in the rate of interest, the price of the imported good, the externalities of the industrial sector, on the dynamic paths of trade balance and economic growth. The comparative dynamic analysis provides some important insights. For instance, the simulation demonstrates that as the tariff rate is increased, the consumption level of the imported good is reduced; the government revenue, the output and two inputs of the public sector are all increased; some of the labor force is shifted from the industrial sector to the public sector; the capital input and output level of the industrial sector are reduced; the price of the service is increased and the service sector’s inputs and output are slightly affected; the consumption levels of the industrial good and the service are slightly increased; The trade balance is deteriorated initially but improved in the long term; and the capital intensities of the three sectors, the wage rate and wealth per household are increased. - In questo studio si esamina un modello a tre settori di piccola economia aperta con importazione di beni e con tariffe. I settori sono quello industriale, i servizi e il settore pubblico. Il modello considera anche l’impatto delle esternalità, della congestione e degli effetti dei beni pubblici sulla produttività, integrando così alcuni modelli di crescita già conosciuti in letteratura. Tra questi troviamo: il modello di crescita di Solow, il modello bisettoriale di Uzawa, i modelli neoclassici delle piccole economie aperte e i modelli di crescita con esternalità, beni pubblici e congestione. Questo modello è incentrato sugli effetti dei cambi nei prezzi, sulla preferenza verso i beni stranieri, sulle variazioni dei tassi di interesse a livello globale, sul prezzo dei beni importati, sulle esternalità del settore industriale, sulle dinamiche della bilancia commerciale e la crescita economica. L’analisi dinamica comparativa fornisce importanti risultati. Per esempio, la simulazione dimostra che, aumentando i prezzi, il livello dei consumi dei beni importati diminuisce; le entrate fiscali, l’output e due input del settore pubblico aumentano; parte della forza lavoro si sposta dal settore industriale a quello pubblico; il livello di input e di output del capitale del settore industriale si riduce; il prezzo dei servizi aumenta e l’input e l’output del settore dei servizi subiscono scarsa influenza; il livello dei consumi di beni industriali e dei servizi aumenta leggermente. La bilancia commerciale inizialmente peggiora per migliorare nel lungo periodo e gli investimenti nei tre settori, le retribuzioni e il benessere delle famiglie crescono.
