Determinants of Customers' Intention to Use Interest Free Banking Products and Factors Affecting Employees' Product Knowledge: the Case of Commercial Bank of Ethiopia
Creators: name: Redi, Abraham
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: The capacity of Interest Free Banks to gain substantial market share in a challenging financial environment, particularly in a dual-banking system like Ethiopia, will primarily hinge on the ability of IFB's to formulate and implement successful marketing strategies. This will require a clear understanding of the attitudes of the potential consumers. On the other hand, in coping with customers need, it is always questionable whether the employees of the bank are having adequate training and knowledge on Islamic banking practices. In addressing the stated problems, this thesis, therefore, examines the determinants of customers' intention to use interest free banking products and factors affecting employees' product knowledge, in the context of Commercial Bank of Ethiopia. A survey approach was used to investigate intention to use and products knowledge of IFB customers and employees respectively. Unstructured questionnaire was used to collect qualitative data on customers' use intention. In general, eight and three hypotheses were developed and tested on customers' intention and employees' product knowledge of the CBE with a sample size of 369 and 77 individuals respectively. Both descriptive and inferential analytical techniques were used. To analyze the relationships among the variables, on the other hand, multiple regression and structural equation modeling (SEM) were employed. The findings of the study on customers' intention showed that, except for Knowledge, all the other variables: Attitude, Social Influence, Perceived Financial Cost and Religious Belief have significant effect on IFB use intention. Moreover, except for Underlying Arabic Terminology, the other two variables: Underlying Sharia' Principles and Training have significant effect on Product Knowledge of employees. Furthermore, chi-square test was used to analyze the association between selected demographic factors and IFB usage intention. The findings of this study have shown that, except for educational level, all other demographic factors found to have an insignificant effect on IFB adoption intention. To sum up, the study on customers' intention contributes towards a better understanding of the customers' expectation. The management of the bank can now comprehend better the factors that influence customers' decision in adopting IFB in order to devise effective marketing strategies to attract customers. Not to mention, the findings of this study should be of value to IFBs in terms of expanding customer base. On the other hand, the study on employees' product knowledge suggests that the bank should train well its employees in order to cope with the current dynamics of the banking industry. Keywords: Intention to Use, Product Knowledge, Commercial Bank of Ethiopia, Interest Free Banking

Year: 2024

description: These days, the use of nutraceuticals is receiving greater attention for the improvement of animal health, animal welfare, and productivity in herd health management. The term “nutraceutical” was coined by combining the words “nutrition” and “pharmaceutical”. It refers to any substance that is derived from food or is a part of food, and it offers medical or health benefits, including disease prevention and treatment. These products can include isolated nutrients, dietary supplements, specific diets, genetically engineered designer foods and herbal products. Nutraceuticals distinguish themselves from other dietary supplements in various ways, including their ability to improve animal well-being and health without leaving any residues in meat consumed by humans. As a result, nutraceuticals can be seen as a blend of drugs and food nutrients, falling somewhere in between. They are considered safe and are recognized as alternative natural feed additives. Nutraceuticals exhibit pharmacological and biological activities, which can help combat drug resistance to antibiotics and often produce synergistic effects. The mode of action of nutraceuticals involves the ingestion of the nutraceutical substance, which is then followed by the release of active substances into the animal’s body. These active substances attach to specific sites and carry out their intended functions. Eventually, they are excreted from the animal’s body.

description: A quantitative characterization of the relationship between molecular sequence and structure is essential to improve our understanding of how function emerges. This particular genotype-phenotype map has been often studied in the context of RNA sequences, with the folded configurations standing as a proxy for the phenotype. Here, we count the secondary structures of circular RNAs of length $n$ and calculate the asymptotic distributions of different structural moieties, such as stems or hairpin loops, by means of symbolic combinatorics. Circular RNAs differ in essential ways from their linear counterparts. From the mathematical viewpoint, the enumeration of the corresponding secondary structures demands the use of combinatorial techniques additional to those used for linear RNAs. The asymptotic number of secondary structures for circular RNAs grows as $a^nn^{-5/2}$, with a depending on particular constraints applied to the secondary structure. The abundance of any structural moiety is normally distributed in the limit $n\to\infty$, with a mean and a variance that increase linearly with $n$.

description: Recent application of neural networks (NNs) to modeling interatomic interactions has shown the learning machines' encouragingly accurate performance for select elemental and multicomponent systems. In this study, we explore the possibility of building a library of NN-based models by introducing a hierarchical NN training. In such a stratified procedure NNs for multicomponent systems are obtained by sequential training from the bottom up: first unaries, then binaries, and so on. Advantages of constructing NN sets with shared parameters include acceleration of the training process and intact description of the constituent systems. We use an automated generation of diverse structure sets for NN training on density functional theory-level reference energies. In the test case of Cu, Pd, Ag, Cu-Pd, Cu-Ag, Pd-Ag, and Cu-Pd-Ag systems, NNs trained in the traditional and stratified fashions are found to have essentially identical accuracy for defect energies, phonon dispersions, formation energies, etc. The models' robustness is further illustrated via unconstrained evolutionary structure searches in which the NN is used for the local optimization of crystal unit cells.

description: This meta-analysis was conducted to quantitatively pool the incremental net benefit (INB) of using biologic therapies as an add-on treatment to standard therapy in patients with moderate to severe asthma. We performed a comprehensive search in several databases published until April 2022. Studies were included if they were cost-effectiveness analyses reporting cost per quality-adjusted life-year or life-year on any biologic therapies as an add-on treatment for moderate to severe asthma in patients of all ages. Various monetary units were converted to purchasing power parity, adjusted to 2021 US dollars. The INBs were pooled across studies using a random-effects model, stratified by country income level (high-income countries (HICs) and low- and middle-income countries (LMICs)) and perspectives (health care or payer perspective (HCPP) and societal perspective (SP)) and age group (>12 years and 6–11 years). Heterogeneity was assessed using the I2 statistic. A total of 32 comparisons from 25 studies were included. Pooled INB indicated that the use of omalizumab as an add-on treatment to standard therapy in those aged >12 years was not cost-effective in HICs from the HCPP (n = 8, INB, −6,341 (95% CI, -$25,000 to $12,210), I2=86.18%) and SP (n = 5, -$14,000 (-$170,000 to $140,000), I2=75.64%). A similar finding was observed in those aged 6–11 years from the HCPP in LMICs (n = 2, -$45,000 (-$73,000 to $17,000), I2=00.00%). Subgroup analyses provided no explanations of the potential sources of heterogeneity. The use of biologic therapies in moderate to severe asthma is not cost-effective compared to standard treatment alone.

description: Museums share with libraries and archives the mission of safeguarding objects of historical value, but unlike these institutions, they have undergone several modifications over time to take the focus off the object and give more importance to information and the visitor. Currently they encompass different types of experiences, either through digital and interactive elements, or through new approaches, such as storytelling, which has acted as a protagonist of these transformations. In this sense, the museum in the digital modality, known as virtual museum, plays an important role in this sharing of information and experiences. However, by having different modalities of navigation and interaction, especially in formats that simulate the physical visit, such as virtual tour, they present some problems that have been identified in the literature. With this analysis, we try to understand the role of narratives and the way museums use them in the virtual space to understand the gaps in the use of storytelling in this context.

description: Urinary tract infections (UTIs) are one of the most common bacterial infections in humans. Current knowledge on antimicrobial susceptibility pattern is essential for appropriate therapy. Therefore the aim of the present study was to determine the distribution and antibiotic susceptibility pattern of bacterial strains, with special reference to ESBL, AmpC β-lactamase and MRSA production. A total of 325 clinical isolates were collected from UTI patients from various tertiary care hospitals over a period of 6 months (June 2011 to December 2011). The antimicrobial susceptibility to various drugs was studied by the disc diffusion method as guided by CLSI guidelines. Confirmation of the extended spectrum β-lactamase (ESBL), AmpC β- lactamase and methicillin resistant Staphylococcus aureus (MRSA) production was done by an E-test respectively. Of the 325 isolates, 225 were characterized as gram negative and 77 isolates as S. aureus isolates. The majority (69.3 %) of the isolates were from females compared to males (30.7 %). Prevalence of ESBL and AmpC β-lactamase and the coexistence of the phenotype (ESBL+ AmpC β-lactamase) and MRSA in the urinary isolates were found to be 48.9 %, 20.4 %, 6.2 % and 27.5 % respectively. Ampicillin/sulbactam, norfloxacin should be no longer considered as first line of drugs for UTI, because of high resistance. Parentral drugs such as aminoglycosides, carbapenems and piperacillin/tazobactum can be the alternative choice for complicated UTI. Also, control measures such as judicious use of antibiotics, formulation of infection committee may control the spread of resistance.

description: The large cavities observed in the dust and gas distributions of transition disks may be explained by planet-disk interactions. At ~145 pc, 2MASS J16042165-2130284 (J1604) is a 5-12 Myr old transitional disk with different gap sizes in the mm- and $μ$m-sized dust distributions (outer edges at ~79 and at ~63 au, respectively). Its $^{12}$CO emission shows a ~30 au cavity. This radial structure suggests that giant planets are sculpting this disk. We aim to constrain the masses and locations of plausible giant planets around J1604. We observed J1604 with the Spectro-Polarimetric High-contrast Exoplanet REsearch (SPHERE) at the Very Large Telescope (VLT), in IRDIFS\_EXT, pupil-stabilized mode, obtaining YJH- band images with the integral field spectrograph (IFS) and K1K2-band images with the Infra-Red Dual-beam Imager and Spectrograph (IRDIS). The dataset was processed exploiting the angular differential imaging (ADI) technique with high-contrast algorithms. Our observations reach a contrast of $ΔK, YH$ ~12 mag from 0.15" to 0.80" (~22 to 115 au), but no planet candidate is detected. The disk is directly imaged in scattered light at all bands from Y to K, and it shows a red color. This indicates that the dust particles in the disk surface are mainly $\gtrsim0.3\,μ$m-sized grains. We confirm the sharp dip/decrement in scattered light in agreement with polarized light observations. Comparing our images with a radiative transfer model we argue that the southern side of the disk is most likely the nearest. This work represents the deepest search yet for companions around J1604. We reach a mass sensitivity of $\gtrsim 2-3M_{Jup}$ from ~22 to ~115 au according to a hot start scenario. We propose that a brown dwarf orbiting inside of ~15 au and additional Jovian planets at larger radii could account for the observed properties of J1604 while explaining our lack of detection.

description: In this paper, we study static bistability and mechanical cooling of a dissipative optomechanical cavity filled with a Kerr medium. The system exhibits optical bistability for a wide input-power range with the power threshold being greatly reduced, in contrast to the case of purely dissipative coupling. At the bistable regime, the membrane can be effectively cooled down to a few millikelvin from the room temperature under the unresolved sideband condition, where the effective mechanical temperature is a nonmonotonic function of intracavity intensity and reaches its minimum near the turning point of the upper stable branch. When the system is in the cryogenics environment, the effective mechanical temperature at the bistable regime shows a similar feature as in the room temperature case, but the optimal cooling appears at the monostable regime and approaches the mechanical ground state. Our results are of interest for further understanding bistable optomechanical systems, which have many applications in nonclassical state preparations and quantum information processing.

description: This study explores the added value of haptic games as a novel and innovative form of human-machine interaction that complements and enriches traditional forms of visual and auditory communication. In light of the relatively small number of empirical studies in this field, the above statement becomes more significant. The use of haptic digital games acquires special importance when one considers that these aren't just passive touch applications, where the user does not act. Instead, the user receives information through the passive transmission to his skin. Haptic interaction, on the other hand, is an active touch. Users choose their actions intentionally when exploring and manipulating an object or situation. As a result, these actions provide information about the properties of objects, thereby providing feedback helpful to the player and affecting the gaming experience. The primary objective of this study is to explore the fundamental factors of haptic technology, which can improve human-machine interaction through physical manipulation.

description: The $M$-dimensional unitary matrix $S(E)$, which describes scattering of waves, is a strongly fluctuating function of the energy for complex systems such as ballistic cavities, whose geometry induces chaotic ray dynamics. Its statistical behaviour can be expressed by means of correlation functions of the kind $\left \langle S_{ij}(E+ε)S^†_{pq}(E-ε)\right\rangle$, which have been much studied within the random matrix approach. In this work, we consider correlations involving an arbitrary number of matrix elements and express them as infinite series in $1/M$, whose coefficients are rational functions of $ε$. From a mathematical point of view, this may be seen as a generalization of the Weingarten functions of circular ensembles.

description: The presence of large-scale real-world networks with various architectures has motivated an active research towards a unified understanding of diverse topologies of networks. Such studies have revealed that many networks with the scale-free and fractal properties exhibit the structural multifractality, some of which are actually bifractal. Bifractality is a particular case of the multifractal property, where only two local fractal dimensions $d_{\text{f}}^{\text{min}}$ and $d_{\text{f}}^{\text{max}} (>d_{\text{f}}^{\text{min}})$ suffice to explain the structural inhomogeneity of a network. In this work, we investigate analytically and numerically the multifractal property of a wide range of fractal scale-free networks (FSFNs) including deterministic hierarchical, stochastic hierarchical, non-hierarchical, and real-world FSFNs. Then we demonstrate how commonly FSFNs exhibit the bifractal property. The results show that all these networks possess the bifractal nature. We conjecture from our findings that any FSFN is bifractal. Furthermore, we find that in the thermodynamic limit the lower local fractal dimension $d_{\text{f}}^{\text{min}}$ describes substructures around infinitely high-degree hub nodes and finite-degree nodes at finite distances from these hub nodes, whereas $d_{\text{f}}^{\text{max}}$ characterizes local fractality around finite-degree nodes infinitely far from the infinite-degree hub nodes. Since the bifractal nature of FSFNs may strongly influence time-dependent phenomena on FSFNs, our results will be useful for understanding dynamics such as information diffusion and synchronization on FSFNs from a unified perspective.

This alternative structure is unique when considering a large subspace of possible structural distortions of TiO2 anatase. We propose two routes towards this state and argue that one of them might have been realized in the recently discovered so-called black TiO2.

description: Background National asthma guidelines recommend an outpatient follow-up after hospitalization for asthma. Our aim is determine if a follow-up visit within 30 days after an asthma hospitalization impacts risk for re-hospitalization and emergency department visits for asthma within the following year. Methods This was a retrospective cohort study of claims data of Texas Children’s Health Plan (a Medicaid managed care program) members age 1 to <18 years and hospitalized for asthma between January 1, 2012, and December 31, 2018. Primary outcomes were days to re-hospitalization and emergency department visit between 30 days and 365 days following the index hospitalization. Results We identified 1,485 children age 1 to <18 years hospitalized for asthma. Comparing those with a 30 day follow-up to those without, there was no difference in days to re-hospitalization (adjusted hazard ratio 1.23, 95% Confidence Interval (CI) 0.74-2.06) or emergency department visit for asthma (aHR 1.08, 95% CI 0.88-1.33). Inhaled corticosteroid and short acting beta agonist dispensing were greater in the group completing the 30 day follow-up (means of 2.8 and 4.8 respectively for those with follow-up, 1.6 and 3.5 respectively for those without, p < 0.0001). Conclusion Having a follow-up outpatient visit within 30 days of an asthma hospitalization is not associated with a decrease in asthma re-hospitalization or emergency department visit in the 30-365 day period following the index hospitalization. Non-adherence to regular use of inhaled corticosteroid medication was high in both groups. These findings suggest need for improvement in the quality and quantity post hospital asthma follow-up.

Optimization of Process Parameters for the Extraction of Oil from Mango Seed Kernel (Mangifera indica) for Cosmetics Application
Creators: name: Kemal, Mustefa
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: The main aim of the study was to determine the optimum operating condition for the extraction of oil from mango seed kernel. For this, particle size range of 0.25 mm - 0.5 mm, 0.5 mm - 1.5 mm and 1.5 mm – 3 mm, solvent type hexane, ethanol and petroleum ether and extraction time of 2 hr, 4 hr and 6 hr were considered for optimization. A general factorial design was applied to investigate the effect of process variables on oil yield. Maximum oil yield of 84.81% was obtained for particle size range of 0.25 mm - 0.5 mm at extraction time of 6 hr and with solvent type hexane followed by a yield of 83.33% at particle size range 0.25 mm - 0.5 mm, solvent type petroleum ether and 6 hour extraction time. And minimum oil yield of 18.88% was obtained for particle size range 1.5 mm – 3 mm at extraction time of 2 hr and with solvent type ethanol. ANOVA analysis was showed significant effect of particle size, solvent type and extraction time on oil yield (P value < 0.05). When the particle size range decreased from 1.5 mm – 3 mm to 0.25 mm - 0.5 mm the oil yield increased from 64.07% to 84.81% for solvent type hexane and for 6 hr extraction time. As extraction time was increased from 2 hr to 6 hr the oil yield increased from 57.41% to 84.81% for solvent type hexane and particle size range 0.25 mm - 0.5 mm. Quadratic regression model equations were obtained to describe the effect of variables on the oil yield. The physicochemical properties (total phenolic content, unsaponifiable matter, iodine value, acid value, saponification value, moisture and volatile matter, pH, viscosity, refractive index and specific gravity) of the oil extracted under optimum condition were determined and compared to those of the commercial available mango kernel oil and Indian standards for mango kernel fat. It was found that the physicochemical properties are within the standard except the acid value which is slightly higher. The result also indicated that there is a presence of high unsaponefiable matter (3.85%) and phenolic content (115mg/g for ethanol extract, 83.2mg/g hexane extract and 79.6mg/g for petroleum extract) in the mango kernel oil (obtained from local variety) which makes the oil suitable for cosmetics application.

description: It is widely known that rheumatoid arthritis (RA) is associated with articular bone damage. However, there is still not enough information on whether the inflammatory process can deteriorate bone microstructure outside the joint as well. Furthermore, the impact of RA on the microscopic structure of cortical and trabecular bone, including parameters of bone microarchitecture, strength, and geometry after one remodelling cycle, has not been determined, yet. Therefore, this study investigated possible alterations in both cortical and trabecular bone compartments of the femur in a rat model of adjuvant-induced arthritis (AA) 28 days post disease induction. AA was generally evoked by a single intradermal injection of
suspension of heat-inactivated Mycobacterium butyricumin incomplete Freund’s adjuvant. We have found that AA resulted in inflammation as evidenced by increased hind paw swelling, decreased levels of circulating albumin, and elevated levels of nitrite/nitrate, interleukin-1β. Detrimental changes in examined bone parameters related to microarchitecture, strength, and geometry were revealed in AA rats. Overall, AA was associated with bone loss, decreased bone mineral density in both
cortical and trabecular bone compartments, as well as reduced mechanical competence, and more intense vascularization in the cortical bone. According to our results, AA-related inflammation caused structural degradation of cortical and trabecular bone quality, as well as mechanical weakness in the femoral diaphysis leading to bone fragility after only one remodelling cycle. The findings focused on the femoral diaphysis, which is located outside the joint, are the first in this field of research.

description: A computer-controlled transient viscoelastometer, which is an adaption of the Rheovibron, has been developed to study the mechanical stress relaxation of amorphous materials over a range of more than five decades in time. The instrument was used to investigate the degree of non-exponentiality of the tensile stress autocorrelation function of AgI---Ag2SO4---Ag2WO4 and Ge---As---Se glasses. Upon variation of the composition, both ternary systems show large variations of the smearing of the calorimetric glass-transition anomaly. For most cases low-noise decay functions could be observed which are well fitted by stretched exponentials. For 50AgI·25Ag2SO4·25Ag2WO4 an exceptionally broad distribution of relaxation times is found. This is consistent with the sub-Tg specific heat peak previously observed in these mixed oxyanion glasses. For pure amorphous selenium two distinct relaxation processes are observed.

description: Plasma echo is a dramatic manifestation of plasma damping process reversibility. In this paper we calculate temporal and spatial plasma echoes in graphene in the acoustic plasmon regime when echoes dominate over plasmon emission. We show an extremely strong spatial echo response and discuss how electron collisions reduce the echo. We also discuss differences between various electron dispersions, and differences between semiclassical and quantum model of echoes.

description: The low-frequency dynamical response of an Anderson insulator is dominated by so-called Mott resonances: hybridization of pairs of states close in energy, but separated spatially. We study the effect of interaction on Mott resonances in the model of spinful fermions (electrons) with local attraction. This model is known to exhibit a so-called pseudogap: a suppression of the low-energy single-particle excitations. Correspondingly, the low-energy dynamical response is also reduced. However this reduction has mostly quantitative character. In particular, the Mott formula for frequency-dependent conductivity preserves its functional asymptotic behavior at low frequencies, but with a small numerical prefactor. This result can be explained in terms of Mott resonances for electron pairs instead of single electrons.

description: To investigate the knowledge and perceptions of physicians on the role of modeling studies in asthma, using a modified Delphi procedure. Group opinions among a panel of respiratory experts were obtained using two online questionnaires and a virtual scientific workshop. A consensus was pre-defined as agreement by >75% of participants. From 26 experts who agreed to participate, 22 completed both surveys. At the end of the process, the panel rated their own understanding of modeling as good (77%) but that among physicians in general as poor (77%). Participants agreed that data from modeling studies should be used, at least sometimes, to inform treatment guidelines (91%) and could be useful for guiding clinical decisions (100%). Perceived barriers to using modeling studies were ‘A lack of understanding’ (81%) and ‘A lack of standardized methodology’ (82%). Based on data from two modeling studies, no consensus was reached on physicians recommending regular inhaled corticosteroids (ICS) versus as-needed therapy for patients with mild asthma, whereas 77% agreed that they would recommend regular ICS over maintenance and reliever therapy for ≥80% of their patients with moderate asthma. No consensus was reached on the value of modeling data in relation to empirical data. There is overall support among respiratory experts for the usefulness of modeling data to guide asthma treatment guidelines and clinical decision making. More publications on modeling data using robust models and accessible terminology will aid the understanding of physicians in general and help clarify the evidence-based value of modeling studies.

description: Within the trln-formalism we investigate the vacuum interaction of cosmic strings and the influence of strings width on this effect. For the massless real scalar field we compute the Casimir contribution into the total vacuum energy. The dimensional-regularization technique is used. It is shown that the regularized Casimir term contains neither the UV-divergences, nor the divergences related with the non-integrability of the renormalized vacuum mean of the energy-momentum tensor.

description: Degree sequence (DS) problems are around for at least hundred twenty years, and with the advent of network science, more and more complicated, structured DS problems were invented. Interestingly enough all those problems so far are computationally easy. It is clear, however, that we will find soon computationally hard DS problems. In this paper we want to find such hard DS problems with relatively simple definition. For a vertex $v$ in the simple graph $G$ denote $d_i(v)$ the number of vertices at distance exactly $i$ from $v$. Then $d_1(v)$ is the usual degree of vertex $v.$ The vector $\mathbf{d}^2(G)=( (d_1(v_1), d_2(v_1)), \ldots,$ $(d_1(v_n), d_2(v_n))$ is the {\bf second order degree sequence} of the graph $G$. In this note we show that the problem to decide whether a sequence of natural numbers $((i_1,j_1),\ldots (i_n,j_n))$ is a second order degree sequence of a simple undirected graph $G$ is strongly NP-complete. Then we will discuss some further NP-complete DS problems.

description: We present the implementation of a next-to-leading-order plus parton-shower event generator for the hadronic production of a heavy charm quark accompanied by a leptonically-decaying $W$ boson in the POWHEG BOX RES framework. We consider both signatures, i.e. $pp\to c\, \ell^- \barν_{\ell}$ and $pp\to \bar{c} \,\ell^+ ν_{\ell}$, and we include exactly off-shell and spin-correlation effects, as well as off-diagonal Cabibbo-Kobayashi-Maskawa contributions. We present particle-level results, obtained interfacing our code with the Herwig7.2 and Pythia8.3 shower Monte Carlo event generators, including hadronization and underlying-event effects, and compare them against the data collected by the CMS Collaboration at $\sqrt{s}=13$ TeV.

The Political Economy of Municipal Spending: Evidence from Chicago’s Menu Program

description: This paper investigates the political economy of conspicuous public spending. It defines conspicuous public spending as spending intended to signal competency to voters to win an election but does not have substantial returns to voters compared to other projects. An example would be a politician choosing to develop a new set of murals across the community instead of installing much-needed bollards for public safety. A simple career-concerns model featuring a temporal tradeoff between conspicuous and inconspicuous expenditures and political experience demonstrates this effect in a rational-choice framework. The model has two critical implications. Firstly, unexpected increases in conspicuous expenditures help politicians get re-elected. Secondly, less-experienced politicians spend more conspicuously than their established counterparts. This paper uses data from Chicago's Aldermanic Menu Program to test these implications. The first implication is confirmed via a simple discrete-choice analysis. Differences-in-differences methods further show some evidence for the second implication. However, counter to the model, the Differences-in-Differences study shows an effect that decays before the next election. Furthermore, a regression discontinuity analysis also shows an impact, which the model does not predict. This paper concludes by exploring alternative hypotheses that may be driving the result.
