In online labor markets, millions of paid tasks are performed by workers every day. We solve the stable pricing problem, that is, given the information about tasks and workers, to find a revenue-maximizing mechanism – pricing and allocation – that is stable (where no worker or task is treated unfairly), and truthful (tasks reveal their true needs). We propose two truthful, stable mechanisms nam...

Small and medium-sized enterprises (SMEs) faces much more severe financial constraints compared to large mature companies it is vulnerable market imperfection. To alleviate SMEs’ constraints, Public Credit Guarantee Schemes (CGSs) have been introduced widely used around the world. Having provided a thorough analysis of effectiveness traditional CGSs, we introduce an innovative financing contrac...

Six hens pecked a key (Experiment 1) or pushed a door (Experiment 2) to obtain food reinforcement. In both experiments and as an analogue of price changes, the response requirements were varied in two ways: by increasing the number of responses required and by increasing the required force of each response. The two price manipulations (response number and response force) had different effects o...

2. Approach We first define a family of very simple basic investment strategies. We wish to guarantee that the performance of our strategy is close to that of any of the the basic strategies that we may consider, which can be achieved by hedging : distributing our starting capital over all basic strategies. Let δ = δ1, δ2, . . . be a sequence of positive reals, then the basic strategy σδ initia...

The innovation of supply chain financial services can alleviate the plight of SMEs financing difficulties. In the aspect of supply chain finance model, there is a credit guarantee financing model, which is different from the simple external financing and internal financing mode of supply chain. Based on this, this paper studies the decision-making of supply chain finance under the partial credi...

In an auction market where the price of each selling item is restricted to an admissible interval (price rigidities), a Walrasian equilibrium usually fails to exist. Dreze (1975) introduced a variant concept of Walrasian equilibrium based on rationing systems, named constrained Walrasian equilibrium, for modelling an economy with price rigidities. Talman and Yang (2008) further refined the conc...

How does a boundedly rational optimizing agent make decisions? Can such an agent learn to behave rationally? We address these questions in a standard regulator environment. Our behavioral primitive is anchored to the shadow price of the state vector. The regulator forecasts the value of an additional unit of the state tomorrow, and uses this forecast to choose her control. The value of the cont...

We consider the complexity of decision making with regards to predatory pricing in multimarket oligopoly models. Specifically, we present multimarket extensions of the classical single-market models of Bertrand, Cournot and Stackelberg, and introduce the War Chest Minimization Problem. This is the natural problem of deciding whether a firm has a sufficiently large war chest to win a price war. ...
