This paper analyzes the problem raised by quality provision in globalizing economies. When quality is a credence attribute, there is a signaling problem and quality drops to its minimum level. A way out of this under-provision equilibrium consists to rely on certification. However certification of goods involves costs, most of which are fixed, because to credibly signal quality, the certification process has to be carry out by an independent authority above all suspicion. The certification costs, which might justify a centralized intervention, become a major force in deciding market structure. Then in a given population the rate of certification depends on the consumers' wealth and size. If the population is too poor the market for certification collapses... |

Economic models of trade in endangered species products often do not incorporate four focal arguments in the policy debate over trade bans: 1) law-abiding consumers may operate in another market, separate from illegal consumers, that trade would bring online; 2) legal trade reduces stigma, which affects demand of law-abiding consumers; 3) laundering may bring illegal goods to legal markets when trade is allowed; 4) legal sales may affect illegal supply costs. This paper analyzes systematically which aspects of these complicated markets, separately or in combination, are important for determining whether limited legalized trade in otherwise illegal goods can be helpful for achieving policy goals like reducing poaching. |

The notion of indirect separability is exploited to derive a new multistage demand system. The model allows a consistent parameterization of demand relations at various budgeting stages and it fulfills the requirement of flexibility while satisfying separability globally. Two propositions are derived to characterize flexible and separable functional forms, which lead to the specification of a flexible and separable translog (FAST) demand system. The model is particularly attractive for modeling large complete demand systems, and is illustrated with an application to Canadian food demand. |
