This article develops the concept of recombinant urbanization to show how agrarian landed property and land‐based caste/class relations shape the production of post‐liberalization urban real estate markets in India. I focus on two interrelated but differentiated agrarian property regimes in western Maharashtra to argue that real estate development is building on prior uneven agrarian land markets, which were themselves sociotechnically produced by colonial and postcolonial development politics. Through an examination of the organizational form of sugar cooperatives, which mediated agrarian capitalism in an earlier era, I track how these primary agricultural cooperatives are now being reorganized into real estate companies, sometimes with former sugarcane growers as company shareholders. The same caste‐based political and social capital that made sugar cooperatives possible in a capitalist agrarian society is now being leveraged by agrarian elites to ease their own and their constituents’ entry into an urbanizing economy. The concept of recombinant urbanization opens new methodological entryways to analyze the entangled agrarian and urban question in predominantly agrarian and late liberalizing societies. 相似文献

This paper examines the issue of multiplicity of Markov Perfect equilibria in alternating move repeated games. Such games are canonical models of environments with repeated, asynchronous choices due to inertia or replacement. Our main result is that the number of Markov Perfect equilibria is generically finite with respect to stage game payoffs. This holds despite the fact that the stochastic game representation of the alternating move repeated game is “non-generic” in the larger space of state dependent payoffs. We further obtain that the set of completely mixed Markov Perfect equilibria is generically empty with respect to stage game payoffs. 相似文献

This study measures productivity growth on Irish dairy farms over the period 1984–2000. A total factor productivity index
is constructed for the dairy system and is decomposed into technical change, efficiency change, and changes in scale efficiency.
This is achieved by estimating a stochastic output distance function model of the production technology in use on Irish dairy
farms. Overall, productivity on Irish dairy farms grew by 1.2% per annum over the sample period.

基于贝叶斯SV模型的通货膨胀水平与不确定性关系研究 总被引：1，自引：0，他引：1
针对我国通货膨胀水平与不确定性的时变性特征,分别建立了随机波动均值模型和非对称随机波动均值模型,在MCMC稳态模拟的框架下研究了我国通货膨胀水平与不确定性的动态关系。研究结果表明:我国通货膨胀不确定性中具有明显的持续性特征,并且通胀水平中虽然不存在与金融资产价格运动类似的杠杆效应,但是正向冲击增加了经济行为主体对未来不确定性的预期,由此将导致明显的\"示范效应\"和\"追涨效应\";特别是风险溢出系数的贝叶斯估计为正,反映了通胀不确定性对通胀水平的正向影响作用,说明我国目前的货币政策框架中含有相机抉择的成分因素。 相似文献

利用社会网络分析、地理空间分析和随机面向对象模型,基于2006年与2016年中国高校合作论文数据,探究中国高校知识合作网络演化特征及网络演化影响因素。研究表明：中国高校间合作日益频繁,高校知识合作网络演化处于活跃期;高校知识合作网络具有小世界特征,网络呈现出核心—半边缘—边缘结构,985高校和211高校占据网络重要位置;网络联系呈现出东密西疏的空间结构,联系强度存在地理距离衰减规律;高校知识合作网络存在7个内部成员较为稳定的高校社团,社团具有空间连片式集聚特征;中国高校知识合作网络演化受网络结构、多维邻近性以及高校自身特征等因素的影响,最为关键的推动因素是地理邻近性、互联网发达程度、认知邻近性和制度邻近性。 相似文献

We develop a nonsmooth approach to envelope theorems applicable to a broad class of parameterized constrained nonlinear optimization problems that arise typically in economic applications with nonconvexities and/or nonsmooth objectives. Our methods emphasize the role of the Strict Mangasarian–Fromovitz Constraint Qualification (SMFCQ), and include envelope theorems for both the convex and nonconvex case, allow for noninterior solutions as well as equality and inequality constraints. We give new sufficient conditions for the value function to be directionally differentiable, as well as continuously differentiable. We apply our results to stochastic growth models with Markov shocks and constrained lattice programming problems. 相似文献

We analyze how hiring and firing costs as well as firing regulatory delays affect firms’ hiring, firing, and relocation policy with a stochastic control model. These frictions are substantial; e.g. the firing delay can be almost a year. In the model hiring and firing costs depend on the firm size and the number of people hired or fired. Based on our simulations, hiring and firing elasticities without relocation are highest with respect to demand and productivity volatility and the hiring and firing variable costs. The elasticity of firing due to relocation is highest with respect to the firm-sized firing cost. 相似文献

Volatility swaps and volatility options are financial products written on discretely sampled realized variance. Actively traded in over-the-counter markets, these products are often priced by continuously sampled approximations to simplify the computations. This paper presents an analytical approach to efficiently and accurately price discretely sampled volatility derivatives, under a general stochastic volatility model. We first obtain an accurate approximation for the characteristic function of the discretely sampled realized variance. This characteristic function is then applied to price discrete volatility derivatives through either semi-analytical pricing formulae (up to an inverse Fourier transform) or an efficient Fourier-cosine series method. Numerical experiments show that our approximation is more accurate in comparison to the approximations in the literature. We remark that although discretely sampled variance swaps and options are usually more expensive than their continuously sampled counterparts, discretely sampled volatility swaps are more prone to be cheaper than the continuously sampled counterparts. An analysis is then provided to explain why this is the case in general for realistic contract specifications and reasonable model parameters. 相似文献
