The successful negotiation of the 1977 Torrijos–Carter Treaty inaugurated a new historical era in the Republic of Panama. Politically, the implementation of the Treaty from 1979 to 1999 transformed what, since 1903, had been a protectorate of the United States into a fully sovereign republic. Economically, the integration of the canal into Panama´s internal economy, and that of the country in the global market, created new opportunities for the development of the country. The treaty also put an end to the dispute between Panama and the United States over the control of the rent and revenues produced by the canal, transferring it to the government of the Republic of Panama, and so creating an unprecedented source of resources for investment. More than forty years on, however, Panama faced a combination of sustained (but uncertain) economic growth, persistent social inequity, constant environmental degradation, obsolescence of its institutional system, and increasing internal political tensions, all expressions of the contradiction between the natural organization of the territory of Panama, and the spatial organization of its economy, society and government imposed and maintained since the European conquest of the 16th century. This contradiction is also aggravated by the dispute over control of the canal rent between different sectors of Panamanian society. In short, the country is in a transition stage in its development, which may lead it to overcome the contradiction in developing into a prosperous and equitable republic, or into increasing conflicts that may worsen the contradictions inherent to a centralist and authoritarian tradition of governance.

Climate change is one of the most dangerous threats to human beings, and therefore, it is of great importance for the researchers to inform the policy makers of the threats of climate change and global warming. One of the main causes of climate change is the greenhouse gas emissions, particularly CO2 emissions. In this paper, we try to find a nexus between energy consumption, CO2 emissions, and economic growth in the United States, China, and India, known as three most polluting countries in the world. For this purpose, we applied the wavelet correlation and the partial wavelet coherence approaches during the period 1971–2013. The empirical results for the United States show that the GDP is positively correlated with the CO2 emissions and energy consumption in all frequencies. For China, there is a significant positive relationship between the GDP and CO2 emissions/energy consumption for the short-term horizon. However, for India, although there is a significant positive relationship between the GDP and CO2 emissions, the nexus between the GDP and the energy consumption is not clear. Furthermore, the pollution haven hypothesis was confirmed by the obtained empirical results. Based on our study, we suggest the policy makers in these three countries making supportive decisions for the producers to use modern environment-friendly technologies and renewable energies in their products.

In this article, we attempt to examine the nexus of trade, economic growth, and international tourism. We resort to wavelet-based analysis to capture the time–frequency-based lead–lag dynamics of this nexus. Considering the monthly data spanning from January 1999 to February 2018 for the United States, we find the evidence that (a) increasing trade leads to higher tourist inflows (in terms of receipts), (b) tourist receipts are lagged by economic growth, and (c) these relationships are significant in the long term. We believe that these results are crucial for policymakers to frame policies regarding tourism in the United States.

I am honoured to be invited to give this lecture before so distinguished an audience of development economists. For the last 21/2 years I have been director of a project financed by the Canadian Institute for Advanced Research and composed of a group of scholars from Canada, the United States, and Israel.I Our brief is to study the determinants of long term economic growth. Although our primary focus is on advanced industrial countries such as my own, some of us have come to the conclusion that there is more common ground between developed and developing countries than we might have first thought. I am, however, no expert on development economics so I must let you decide how much of what I say is applicable to economies such as your own. Today, I will discuss some of the grand themes that have arisen in my studies with our group. In the short time available, I can only allude to how these themes are rooted in our more detailed studies. In doing this, I must hasten to add that I speak for myself alone; our group has no corporate view other than the sum of our individual, and very individualistic, views.
