Abstract:
Taking robotic patents between 1977 and 2017 and building upon the topic modeling technique, we extract their latent topics, analyze how important these topics are over time, and how they are related to each other looking at how often they are recombined in the same patents. This allows us to differentiate between more and less important technological trends in robotics based on their stage of diffusion and position in the space of knowledge, where some topics appear isolated while others are highly interconnected. Furthermore, we propose a novel approach to match the constructed topics to the IFR classification of service robots based on frequency and exclusivity of words overlapping between them. We identify around 20 topics belonging to service robotics. Our results corroborate earlier findings, but also provide novel insights on the content and stage of development of application areas in service robotics. With this study we contribute to a better understanding of the highly dynamic field of robotics and contribute to new practices of utilizing the topic modeling approach.

Abstract:
For many years, the economies of the Economic and Monetary Community of Central Africa, like most of the world’s economies, have been confronted with numerous fluctuations in the price of raw materials on international markets. For these predominantly extroverted economies, that is, those dependent on export earnings, these price variations have consequences for their macroeconomic performance and the conduct of economic policy. Like most economic crises in the world in the past, the pandemic caused by the new Coronavirus that has been raging since 2020 has also brought with it many changes. Between the confinement measures taken by public authorities to curb the spread of the virus and the resulting slowdown in global economic activity, there has been an inevitable significant drop in global oil demand. The direct consequence of such a scenario is the fall in oil prices on world markets, which is very bad news for the public finances of oil-exporting countries. The main objective of this report is to analyze the effects of oil price fluctuations on the conduct of monetary policy in the CEMAC. We start from the observation that oil shocks are the source of strong inflationary pressures in these economies. It is the responsibility of monetary policy to ensure price stability. Thus, after analyzing the effects of oil price fluctuations on the world economy as well as the macroeconomic and financial implications of these fluctuations on the economies in 2020, we use a Vector Auto Regressive model to analyze the contribution of oil price shocks on the historical dynamics of macroeconomic variables in the various CEMAC countries between 2001 and 2020. Then, we use a Panel Smooth Transition Regression model to analyze the impact of oil price changes on monetary policy in the CEMAC.
