The aim of this paper is to examine and conduct a comparative economic analysis between Pakistan and Bangladesh based on different economic indicators from 1971 to 2020. The methodology used in this study is primarily qualitative, with data mainly obtained from secondary sources. The findings of the study suggested that in terms of economic and social development, Bangladesh clearly surpassed Pakistan in all the domains. Bangladesh’s progressive and consistent economic approach with emphasis on economic empowerment of their population was the key towards Bangladesh’s success. Bangladesh dominated the following economic indicators: Current account balance, GDP growth rate, GDP per capita growth rate, and social development. In contrast, Pakistan lacked behind due to immersive political and economic instability caused by inconsistent political regimes and economic policies. The findings revealed that Pakistan’s: Exports % of GDP, Trade balance, Net income, Current account balance, GDP annual growth rate, GDP per capita annual growth rate, portrayed better performance in the first economic phase (1971-2000) than in the second economic phase (2000-2020).

This study investigates the impact of real exchange rate misalignment on Pakistan’s economic growth across different identified threshold levels. The research makes three significant contributions to the applied macroeconomics literature. First, it employs a dynamic regression model to assess the primary factors determining the equilibrium real exchange rate (ERER). Second, it examines the asymmetric impact of real exchange rate misalignment on Pakistan’s economic growth using the nonlinear autoregressive distributed lag (NARDL) model. Third, through a threshold regression model inspired by Hansen (Hansen, Econometrica 68:575–603, 2000), it identifies the threshold values of the Pakistani rupee that can either promote or hinder economic growth. The study concludes that the Pakistani rupee experienced significant periods of both undervaluation and overvaluation between 1982 and 2022. Moreover, the analysis establishes that overvaluation impedes Pakistan's economic growth, while undervaluation stimulates it. Our findings suggest that the undervaluation of the Pakistani rupee promotes economic growth up to an estimated threshold of a 10.025% deviation from ERER is reached. In contrast, an overvalued Pakistani rupee can stimulate economic growth up to a 9.346% threshold. The study implies that Pakistan should avoid both overvaluation and undervaluation beyond these identified thresholds to sustainably enhance economic growth. Additionally, it recommends that appropriate fiscal and monetary policies be pursued to maintain the exchange rate close to the equilibrium rate.

These models are based on the estimation of a reduced-form ERER regression.

See Amor et al. ( 2023 ) for details.
According to Frenkel and Ros ( 2006 ), the RER affects unemployment through three channels: macroeconomic, labor-intensity, and development. The traditional argument is that depreciation boosts the competitiveness of domestic firms; thus, a depreciated RER boosts the competitiveness of domestic products, resulting in an increase in net exports. The subsequent growth in exports boosts demand for domestic activities, resulting in higher output and employment levels.
The same results were obtained using the Augmented Dickey-Fuller ( ADF ) and Phillips-Perron ( PP ) unit root tests.
The PEER approach serves as a long-run equilibrium concept employed to ascertain RERMIS through a filtered series (Driver and Westaway 2005 ). According to Kucsera ( 2007 ), this method ensures a smoother ERER compared to the BEER approach and is more easily interpretable.

After analyzing annual data, we determined that a maximum of four lags is optimal. This selection of lags is based on the AIC and SBC criteria.

CASE STUDY 2 Comparative Economic Development: Pakistan & Bangladesh. Group 1: Alcontin, Rocel. Ano-os, Antonette. Austria, Kyla. Archival, Allemar. Balajadia, Axl Loi. ... In connection, the differences in social development in Bangladesh and Pakistan are not as overwhelming as would be found in a comparison with Sri Lanka, physical facilities ...
This not only facilitates smoother economic activities but also contributed to improved accessibility, connectivity and overall well-being of the population. V.
