Doppelganger-Inspired Change Effect Model of Faculty Global Cultural Competency

Our student populations' diversity now includes more than just African Americans, Native Americans, Latinos. We are now more representative of a wider range of cultural backgrounds. This shift brings fresh challenges of educator unpreparedness to identify with the unique cultures of international students. The cultural dissonance that international students face compounds this challenge. The cultural unawareness and misconceptions may be generated from both educators and students. The DICE model is inspired by an extensive review of the literature and a qualitative case study methods application. It is a process of fostering global cultural empathy and preparedness of educators by linking such preparedness to evaluating negative attitudinal influences that may block people from changing their thinking, which in turn will negatively impact global empathy preparedness. This is a valid linkage given the influence culture has on attitudes and vice versa and is true in the context of developing global empathy.

Topological Properties in a Λ/V-Type Dice Model

We studied a non-interacting Λ/V-type dice model composed of three triangular sublattices. By considering the isotropic nearest-neighbor hoppings and the next-nearest-neighbor hoppings with the phase, as well as the quasi-staggered on-site potential, we acquired the full phase diagrams under the different fillings of the energy bands. There are abundant topological non-trivial phases with different Chern numbers C=±1, as well as higher ones ±2,±3 and a metal phase in several regimes. In addition, we also checked the bulk–edge correspondence of the system by analyzing the edge-state energy spectrum.

Relative Prices and Climate Policy: How the Scarcity of Nonmarket Goods Drives Policy Evaluation

Climate change not only impacts production and market consumption but also the relative scarcity of nonmarket goods, such as environmental amenities. We study fundamental drivers of the resulting relative price changes, their potential magnitude, and their implications for climate policy in Nordhaus’s Dynamic Integrated Climate-Economy (DICE) model, thereby addressing one of its key criticisms. We propose plausible ranges for these relative prices changes based on best available evidence. Our central calibration reveals that accounting for relative prices is equivalent to decreasing pure time preference by 0.6 percentage points and leads to a more than 50 percent higher social cost of carbon.

SELFISH BUREAUCRATS AND POLICY HETEROGENEITY IN NORDHAUS’ DICE

Nordhaus’ seminal DICE model assesses first-best climate policy, a useful but unrealistic yardstick. I propose a measure of policy inefficacy if carbon prices are heterogeneous and use observed prices to recalibrate the DICE model. I introduce a Niskanen-inspired model of climate policy with selfish bureaucrats, and calibrate it to carbon dioxide emissions in the European Union and the policy models used by the IPCC. This model also implies a measure of policy inefficacy that I use to recalibrate DICE. The optimal global mean temperature is 1°C perhaps 2°C higher in the recalibrated than in the original DICE model.
