| Abstract: | I develop a model of group decision-making, in which a committee generates proposals and holds open discussions, but the ultimate decision is either taken by a leader (decision by authority) or by majority vote. Optimal communication processes are studied that combine both cheap talk statements (proposals) and costly state verification (discussions). I show that by favouring one particular agent — the leader — authoritative decision-making reduces rent-seeking discussions and often results in a higher decision-quality relative to majority decision-making. Institutions which guarantee a "right to voice" by separating the roles of decision maker and discussion leader may further improve efficiency. |

| Abstract: | In this paper I will introduce a new political economy model, where there exists a competition amongst two political candidates, which aim to set a policy which enables them to win elections, max- imising the probability of winning. I will show that, if taxes neces- sary to repay the debt are not lump sum but proportional to income, we have dramatic distorting effect on the labour supply. The prob- lem is exacerbate once we take into account that the Government set taxes in order to favour the most in‡uencing social group. As a consequence, effective marginal tax rates are differentiated amongst social groups and thus the burden of public debt is not equally borne. |

| Abstract: | A general collective decision problem is analysed. It consists in many issues that are interconnected in two ways: by mutual constraints and by connections of relevance. The goal is to decide on the issues by respecting the mutual constraints and by aggregating in accordance with an informational constraint given by the relevance connections. Whether this is possible in a non-degenerate way depends on both types of connections and their interplay. One result, if applied to the preference aggregation problem and adopting Arrow''s notion of (ir)relevance, gives Arrow''s Theorem, without excluding indifferences unlike in the existing general aggregation literature. |
