1. Theta synchronization as a neural marker of flexible (re-)use of socio-cognitive mechanisms for a new category of (artificial) interaction partners

Abstract

Previous work shows that in some instances artificial agents, such as robots, can elicit higher-order socio-cognitive mechanisms, similar to those elicited by humans. This suggests that these socio-cognitive mechanisms, such as mentalizing processes, originally developed for interaction with other humans, might be flexibly (re-)used, or "hijacked", for approaching this new category of interaction partners (Wykowska, 2020). In this study, we set out to identify neural markers of such flexible reuse of socio-cognitive mechanisms. We focused on fronto-parietal theta synchronization, as it has been proposed to be a substrate of cognitive flexibility in general (Fries, 2005). We analyzed EEG data from two experiments (Bossi et al., 2020; Roselli et al., submitted), in which participants completed a test measuring their individual likelihood to adopt the intentional stance towards robots, the intentional stance (IST) test. Our results show that participants with higher scores on the IST, indicating that they had higher likelihood of adopting the intentional stance towards a robot, had a significantly higher theta synchronization value, relative to participants with lower scores on the IST. These results suggest that long-range synchronization in the theta band might be a marker sociocognitive process that can be flexibly applied towards non-human agents, such as robots.

3. Information Transmission and Ownership Consolidation in Aid Programs

Author

Abstract

We investigate the degree of leeway donors of foreign aid should grant to recipient governments when their preferences over how to implement the aid are different, and both the donor and recipient possess some private information about the most effective policies. Intuitively, our model shows that donors should stay in control of how their aid is spent when their own private information is more important than the private information of the recipient. Less obviously, an increase in the difference of preferences between donors and recipients can increase rather than decrease the leeway that donors should grant the recipients, as the recipients' information gains in importance relative to those of the donors, and recipients become less likely to communicate truthfully. We test the model using dyadic data for 28 bilateral aid donors and 112 recipients, over the 1995–2010 period. Our proxy for “centralized” aid is project aid, while budget aid leaves more leeway to the recipient and thus proxies for “decentralized” aid. In line with the model, misaligned interests and informational asymmetries indeed influence the shares of aid given as budget and project aid. (JEL C23, D82, F33,O1).

5. Read my lips: the role of information transmission in multilateral reform design

Author

Marchesi, S, Sabani, L, Dreher, A, MARCHESI, SILVIA, Dreher, A., Marchesi, S, Sabani, L, Dreher, A, MARCHESI, SILVIA, and Dreher, A.

Abstract

Context-specific knowledge is crucial to crafting multilateral reform programs. Nonetheless local knowledge often consists of unverifiable information, thus the quality of countries' reports depends on the conflict of interests faced by the recipient and the multilateral. We compare the performance of a “delegation-scheme” against a “centralization-scheme.” We find that recipients' discretion in the choice of reforms (delegation) should only be increased when the countries' local knowledge is strictly more important than the multilateral's information. Conversely, a reduction in the conflict of interests may lead the multilateral in to allowing the recipient less freedom in designing reforms (centralization). Our empirical results support these theoretical predictions

20. Communication and performance in Bank–Fund joint participation

Abstract

In this paper I relate Bank–Fund performance to their willingness (or ability) to communicate. I find evidence that a Bank–Fund simultaneous loan is associated to an increase in economic growth and that such effect is diminished by factors preventing full communication, such as the degree of Bank-Fund competition and the salience of informational asymmetries. Politically motivated loans seem—at least to some extent—stimulate more IMF–WB interaction, which turns out to be associated to a better country’s performance.

21. Liberalizing Art: Evidence on the Impressionists at the End of the Paris Salon

Abstract

We analyze the Paris art market between the government-controlled Salon as a centralized organization of art exhibition and the system liberalized by the Republican government based on competition between independent exhibitions. The jury of the old Salon decided on submissions with a bias toward conservative art of the academic insiders, reducing demand for the outsiders, as confirmed by the impact on prices of the acceptance of Impressionists. With a difference-in difference estimation we provide evidence that the end of the government-controlled Salon in 1880 started the increase of the prices of the Impressionists relative to the insiders.

22. Adoption of an IMF Programme and Debt Rescheduling: An Empirical Analysis

Abstract

The existence of an empirical relationship between the adoption of an IMF programme and the concession of a debt rescheduling by commercial creditors is tested using a bivariate probit model. If countries who have arrangements with the IMF are more likely than others to obtain a rescheduling of their external debt, we could conclude that the adoption of an IMF programme could work as a sort of signal of a country's "good intent" which is thus rewarded with the debt relief. The results confirm the existence of a significant effect of the adoption of an IMF programme on the subsequent concession of a debt rescheduling by private creditors. © 2002 Elsevier Science B.V.
